8 common signs of a weak immune system

A strong immune system works as a shield to protect against infections and diseases caused by pathogens and foreign substances. But sometimes, immunity can weaken, leaving one susceptible to several health issues. Also, the recovery time from these illnesses tends to get longer. Therefore, it is important to recognize the common signs of a weak immune system to maintain overall health and take the necessary precautions after consulting a primary care doctor.

Common signs of a weak immune system
Here are a few common signs of a weakened immune system:

  • Frequent instances of infection
    When the immune system becomes weak, there are frequent infections. This happens because there is a decrease in the production of white blood cells and antibodies. These are responsible for fighting off bacteria and other germs that cause infectious diseases. As a result, one frequently experiences mild to severe infections such as the common cold, flu, and ear, urinary tract, and sinus infections.
  • Wounds take time to heal
    Whenever there is a cut, burn, scrape, or any type of wound, white blood cells, antibodies, and essential nutrients flow through the blood to the wound area. This helps the damaged skin layers regenerate faster, so the wound heals quickly without any complications or infections. However, this essential function slows down when one’s immunity is weak. Thus, the skin takes time to regenerate, leading to slow wound healing.
  • Frequent allergies
    With the immune system losing its strength, there is an onset of frequent allergies. A person who has never experienced any allergic symptoms may become susceptible as their immunity weakens. Frequently, sneezing, throat irritation, nasal blockage, nose irritation, watery eyes, and headaches will occur. Dust, pollen, animal dander, certain chemicals in the air, pollution, or seasonal changes trigger these.
  • Risk of autoimmune diseases
    Autoimmune diseases occur when the body accidentally starts to attack healthy cells, mistaking them for pathogens. This can happen due to several factors, such as underlying health conditions or gene mutations. As a result, the immune system’s activity becomes abnormally high or slow. Some common autoimmune diseases that cause the immune system to become weak include Crohn’s disease, lupus, ulcerative colitis, and rheumatoid arthritis.
  • Recover time increases
    The immune cells, or white blood cells, contain essential nutrients such as different types of proteins and compounds. Whenever one falls sick, the production of these cells increases to help the body recover. However, when the immune system is weak, there is a slowdown in releasing these cells. With a low number of immune cells, there is a deficiency in the number of nutrients flowing through the body. Therefore, one cannot get healthy sooner after any sickness.
  • Frequent digestive issues
    The function of the digestive system depends on the health of the gut. It helps to break down food and keep bowel movements working efficiently. The gut requires the presence of a good amount of healthy bacteria to do this. However, when the immune system becomes weak, the number of good bacteria dwindles. This results in frequent digestive issues such as stomach aches, diarrhea, gas, constipation, or bloating.
  • Constant fatigue
    A weak immune system means that the body’s defenses are weak. This can cause chronic fatigue or a persistent feeling of tiredness. Other symptoms often accompany this type of tiredness. These include constant body pain and aches in the muscles and joints. It becomes difficult to do routine activities. There is a disruption in one’s productivity levels at home and at work. The constant tiredness from a weak immune system doesn’t go away even after rest.
  • Significant hair loss
    The immune cells contain different types of proteins. Some of these proteins are processed by the body to help grow and regenerate hair follicles. With the immune system weakening, the health of the hair follicles is also affected. This can lead to prominent hair loss. While losing some strands of hair in a day is normal, it can cause concern if the hair starts to fall significantly, such as in clumps.

Measures to take to strengthen the immune system
Multiple factors contribute to a strong immune system. These include a person’s genetic makeup, overall health, and family medical history. In addition, there are several measures that one can take to strengthen and support it for better health. These are as follows:

  • Eat balanced and nutritious meals daily
    Including whole and fresh foods in one’s meals and snacks is important. These include a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats. All these have essential vitamins, minerals, and antioxidants that support the immune system’s functions.
  • Always stay hydrated
    Drinking sufficient fluids throughout the day is important to keep the immune system working optimally. Water helps flush out toxins from the cells, while the electrolytes from other fluids help keep the cells functioning well. Fresh fruit juices, soups, smoothies, and herbal teas are great for staying hydrated all day.
  • Follow an exercise routine
    Doing moderate physical activity daily or a couple of times every week helps improve overall health, including the immune system. Walking, running, swimming, or low- to mid-intensity workouts help to improve blood circulation, control blood sugar levels, and keep blood pressure under check.
  • Maintain a regular sleep routine
    The body requires adequate sleep to keep the immune system healthy. When one sleeps for regular hours every day, their body can repair and regenerate efficiently. This enables the immune cells to fight off sickness and infections quickly.
  • Learn to manage stress
    One of the significant effects of chronic stress over the long term is the weakening of the immune system. Due to stress, the body produces a high level of cortisol and norepinephrine hormones. These increase heart rate, blood pressure, and blood sugar levels, making one more prone to illnesses and infections. Therefore, finding ways to manage and deal with stress is important.

Key things to know about macular degeneration

Macular degeneration is an eye disorder that affects the macula, a tiny part of the retina that provides sharp central vision. The most common kind of this disease is age-related macular degeneration (AMD), which affects many people in our country over 60 years. While there is no cure for macular degeneration, several treatments and lifestyle changes help manage the symptoms and improve your vision so that it does not interfere with everyday life. What are the types of macular degeneration? There are two common types of the condition: Wet or exudative macular degeneration This is the more common type. It occurs when the tiny blood vessels in front of your retina get damaged and leak fluid into your eye, causing swelling, redness, and dampness. The condition can affect your central vision and cause blurry patches in the center. Central vision is the area you see directly in front of you. Dry or atrophic macular degeneration Also known as senile macular degeneration, this condition occurs when the retina does not receive sufficient oxygen due to damage from aging; it results in a breakdown of the central part of the retina (the photoreceptors). What causes this eye disorder? The risk factors include genetics and lifestyle ailments, such as high blood pressure, high cholesterol levels, and diabetes. But these do not affect vision overnight; it takes years for the effects to show up. Here is a quick look at the many risk factors of macular degeneration: Age You are at risk of macular degeneration as you get older, especially after age 55. Hence, older adults are advised to go for regular screenings. Genetics You are at a higher risk if one or both parents have this condition. Past eye injury Head or eye trauma can lead to loss of central vision in the future.

Nasal polyps – Symptoms, causes, and management

Nasal polyps can be a symptom of an underlying condition or occur independently. The visible signs and symptoms of nasal polyps include congestion, runny nose, loss of smell, and pressure or pain around your eyes and cheeks. A deviated septum may contribute to nasal polyps. However, they can also occur in people who do not have this condition, such as athletes who blow their noses frequently during exercise routines. Read on to learn more about nasal polyps. What are nasal polyps? Nasal polyps are small, soft growths that develop in the lining of the nasal passages and sinuses. They are also sometimes called nasal tumors or nasal corking. They are not cancerous, contagious, or caused by allergies. Nasal polyps may also be associated with other conditions like chronic rhinosinusitis (CRS), allergic rhinitis (AR), chronic sinusitis (CS), and asthma. Nasal polyps typically develop before the age of 40, and they do not usually cause symptoms until they grow larger or become inflamed or infected.  However, large nasal polyps can block airflow through your nose. If this happens, you may experience sinusitis, headaches, and a stuffy or runny nose. You may also experience difficulty breathing through one nostril at a time if large polyps block the other nostril completely. The result could be an imbalance in oxygen supply to both sides of the body and possible damage to blood vessels in the head (for example, inflammation). Symptoms of nasal polyps In most cases, nasal polyps are painless and cause no symptoms. However, some people with nasal polyps may experience the following symptoms: Congestion or stuffiness A runny nose Loss of smell Loss of taste Pressure or pain around your eyes, cheeks, and teeth Facial pain or headache Snoring Need to clear the throat frequently Frequent bleeding of the nose When to see a doctor?

Atopic dermatitis – Causes, symptoms, and more

Atopic dermatitis (eczema) is a disorder that results in dry, irritable, and inflammatory skin. Though it can affect anyone, young children are more vulnerable to this disorder. The symptoms include recurring (chronic) and sporadic flare-ups, though it is not contagious. Atopic dermatitis patients risk contracting asthma and seasonal and food allergies. Regular moisturizing and skin disease condition-related treatments help alleviate itching and prevent further outbreaks. Using medicated lotions or ointments during treatment is also helpful. Symptoms Depending on an individual’s age, the severity of the condition, and other circumstances, symptoms of atopic dermatitis may vary. Those who have the condition typically experience phases of worsening symptoms, followed by times of improvement or even complete disappearance. The following sections will cover some likely variances in symptoms in more detail. General eczema symptoms Eczema symptoms are usually not severe. The most common signs and symptoms of atopic dermatitis include dry, itchy skin, skin flushing, or weeping sores.  Individuals with severe eczema skin disease may need more intensive care to eliminate their problems. Infections of the skin can also result from persistent touching and scratching. The appearance of the skin area afflicted by atopic dermatitis will vary depending on the frequency of itching and infection. Itching, redness, and irritation can all worsen by rubbing and scratching the skin. What causes eczema skin disease? The underlying etiology of eczema still has to be thoroughly comprehended. The cause, according to scientists, is an overactive immune system. When allergens from the outside come in contact with the skin, the immune system reacts, causing eczema to flare up. A collection of typical flare-up triggers is provided below. Additionally, researchers have shown that the bodies of some people with eczema do not produce enough of the protein filaggrin. This protein is essential for keeping skin healthy and nourished.

Afib – Types, causes, symptoms, and management

Atrial fibrillation (Afib) occurs when the usually stable and regular electrical impulses in the heart’s upper chambers (atria) begin firing chaotically, causing them to quiver or twitch (fibrillate). This can cause blood accumulation and clotting in the atria. These clots can reach the lungs through the blood vessels and cause pulmonary embolism or can reach the brain, resulting in a stroke. Let’s look at the forms, signs, and causes of Afib and its treatment options: Types of atrial fibrillation Afib can be classified as one or more of these: First-diagnosed Afib: Regardless of symptoms or the number or length of episodes, this refers to individuals diagnosed for the first time with Afib. Asymptomatic Afib: This condition is also called silent Afib, given the lack of signs or symptoms. A random electrocardiogram (ECG) could reveal asymptomatic atrial fibrillation. Paroxysmal Afib: Two or more episodes of the conditions that spontaneously resolve within a week are categorized as paroxysmal Afib. Persistent Afib: This refers to two or more episodes of atrial fibrillation that last seven days or more. Long-term persistent Afib: If the condition persists for more than a year, it is referred to as long-term persistent Afib. Permanent Afib: This is a chronic condition that cannot be managed using common treatment options. So here, the patient and doctor decide to stop treatment to get the heart rate back to normal and begin considering other management options. Causes and risk factors Typically, the condition is brought on by coronary artery disease or high blood pressure. Often, atrial fibrillation is triggered by an irregular heartbeat. However, it might occasionally be difficult to determine what triggered such irregularity, and there may be no apparent cause in some cases. In most cases, Afib runs in families, so if one has a family history of the condition, i.e., a close relative has the condition, the likelihood of developing the condition increases.

How to reduce sugar intake and manage blood sugar

How to reduce sugar intake and manage blood sugar

It is a known fact that too much sugar can be devastating for your health. When blood sugar is high, the body produces more insulin, which can lead to several health complications, including prediabetes and diabetes. So, you must cut down on sugar. Choosing healthy snacks and increasing fiber and probiotic intake can help. Moreover, regular exercise is essential. Here are a few tips to lower sugar intake and manage blood sugar levels naturally. Avoid carbohydrates A high intake of carbohydrates has a substantial impact on blood sugar levels. The body breaks down carbohydrates into sugars like glucose, which enters the blood. While the body requires glucose for energy, an excess can be harmful. As the amount of glucose increases, so does the amount of insulin produced by the body, leading to a greater risk of lifestyle disorders. Some foods with an abundance of carbs to stay away from are potato chips and donuts. Control your portion size If you are dealing with frequent blood sugar spikes, monitoring portion size can help. When you eat a large meal, blood glucose increases suddenly. To avoid this, eat smaller meals. You can opt for five to six small meals per day instead of two or three large ones. Use smaller plates, eat slowly, avoid going to restaurants, and keep a food journal. This will not only help manage high blood sugar but also reduce calorie intake, which has several benefits. Consider foods rich in fiber Fiber helps slow the digestion of carbohydrates and sugar absorption, gradually controlling blood sugar. Unsurprisingly, many people with type 1 diabetes can manage their condition better by including more fiber in their meals. Some foods high in fiber are fruits, vegetables, whole grains, and legumes. However, remember that too much fiber can also be a problem. Speak with a doctor to determine the right amount based on your condition.

One must consult a health expert if anxiety is affecting their social life. But first, ensure that any physical health issues are ruled out before consulting them. Most individuals with anxiety disorders need medication or therapy, but coping strategies and lifestyle decisions can also be helpful. Stop and take a breath When you experience an anxiety episode, take a moment to think about what is making you feel uneasy. Usual anxiety symptoms include concerns about a recent or distant event. For example, you can worry that something wrong will happen to you in the future. Or, you can still be upset about something that has already happened in the past. But, whatever your concerns, most anxiety issues stem from not focusing on the present. The next time you feel nervous and get distracted from the present moment, sit down and take some deep breaths to reclaim your composure. You can regain balance and return to the present moment by pausing and taking a few deep breaths. If you have the time, consider advancing this practice by experimenting with breathing techniques. Noting down your triggers One must identify what’s upsetting them to address the underlying cause of their anxiety. One can achieve it by setting aside time to assess your emotions and thoughts. Journaling is a fantastic method to connect with your anxiety triggers. Keep a diary or notepad beside your bed if your anxiety-related thoughts keep you awake at night. You can note down all the issues troubling you. Another technique to identify and understand your nervous feelings is speaking with a friend. Consider the things you can change Worrying about things or incidents that are yet to occur or might never occur can often lead to anxiety.

Breast cancer – Causes, types, and management

Cancer that originates in the breast tissue is called breast cancer. It is the second most common cancer among women in the country. The condition is seen in women more than men. Fortunately, advancements in screening and breast cancer treatment have enabled dramatic improvements in survival rates over the years. The symptoms include changes in the texture and shape of the nipples, discharge from the nipples, and a lump in the breast.  Read on to learn the causes, types, and management options of breast cancer.  Causes of breast cancer Breast cancer occurs when abnormal breast cells divide and multiply more rapidly than healthy cells. These abnormal cells accumulate to form a lump or mass. Doctors have not been able to know the exact cause of breast cancer. However, multiple factors can trigger the chances of developing the disease, and they include: Family history and genetics The risk increases if you have parents or close relatives who have been diagnosed with breast cancer. Having gene mutations such as BRCA1 and BRCA2, which are passed down from parents to children, also increases the risk. Age The risk of breast cancer increases with advancing age.  Gender The risk of developing breast cancer is higher in women than in men.   Personal history of breast conditions The risk increases when an earlier biopsy has indicated atypical hyperplasia of the breast or lobular carcinoma in situ or if cancer has been detected in one breast. Radiation exposure The risk of developing the disease increases if you have been exposed to radiation in your head, neck, or chest areas during past treatments. Hormone replacement therapy Women who use hormone replacement therapy may be more prone to breast cancer. Types of breast cancer Breast cancer  can be categorized into two broad types— invasive and non-invasive.  Invasive breast cancer Cancer that has spread from the place of origin to other parts of the body is termed invasive breast cancer.
