13 foods to avoid to manage MAC lung disease

13 foods to avoid to manage MAC lung disease

MAC lung disease is caused by MAC bacteria (Mycobacterium avium complex) living in the soil and water. They generally affect people with compromised immunity and respiratory ailments, causing symptoms like chronic cough, hemoptysis, fatigue, low-grade fever, shortness of breath, chest pain, and anxiety, which may impede daily activities. Eating the right foods and avoiding the wrong ones is crucial to maintaining one’s quality of life. Here are 13 foods to avoid for MAC lung disease.

Dairy
People with MAC lung disease must avoid dairy products despite their rich calcium content. This is because dairy has been known to impact respiratory health. According to some studies, drinking milk may increase mucus production, leading to congestion. Consuming cheese may also lead to the release of histamines, which can cause airway inflammation.

Salty foods
Foods rich in sodium chloride (or salt) can lead to water retention in the body. This can lead to shortness of breath among those who live with lung disease. Apart from cutting back on table salt, one must also check the ingredients in packed foods, seasonings, and dressings. Confirm that these do not contain more than 300 milligrams of salt per serving. Alternatively, opt for herbs and spices to season food.

Processed meats
Processed meats and cold cuts such as bacon, ham, hot dogs, sausages, and luncheon meats generally contain additives such as nitrates, which help prolong their shelf life. Nitrates have been linked to an increased risk of chronic obstructive pulmonary disorder (COPD), exacerbating lung inflammation. Processed meats also contain sodium nitrites a carcinogenic compound that may increase the risk of cancer. It is best to avoid these meats or look for variants with no added nitrates.

Soda
Soda or sweetened carbonated beverages may significantly aggravate MAC lung disease symptoms. This is because soda contains high amounts of sugar, which can lead to inflammation in the body. Additionally, its carbonation comes from carbon dioxide, which can lead to gas and bloating, affecting the airways and making it difficult to breathe. Ideally, those with MAC lung disease must avoid soda. Switch to non-carbonated flavored drinks like iced tea or juice instead.

Fried foods
Fried foods contain high amounts of unhealthy fats, which can cause inflammation and bloating in the body. This may push on the diaphragm, making it harder to breathe. Over time, regular consumption of these foods may also lead to higher levels of cholesterol, which can worsen symptoms of lung disease.

Chocolate
Chocolate contains caffeine, which may increase the heart rate. Additionally, it also contains high amounts of sugar, which may increase mucus production and worsen symptoms of lung disease.

Bread
Although a staple across many cultures, bread can also worsen symptoms of lung disease. It is known to increase mucus production. Studies have also shown that consuming more than two slices of white bread per day could lead to a higher risk of chronic rhinosinusitis. Research has also linked bread consumption with worsening of asthma symptoms, such as wheezing, chest tightness, or shortness of breath. Switching to whole-grain options may be beneficial, especially for people with respiratory conditions.

Eggs
Eggs are a good source of protein and healthy fats. However, they can also increase mucus production in the body. More research is required to understand why this occurs. In some cases, the body may trigger an immune response against the protein albumin, leading to raised levels of inflammation and mucus production. If one begins to experience these problems, it may be worthwhile to limit egg intake.

Corn
Those with MAC lung disease must avoid corn, as it can negatively impact both the immune and respiratory systems. Corn contains mycotoxins, which can aggravate the risk of several health conditions. It can also lead to increased mucus production, sneezing, itching, and a runny nose.

Dried fruits and vegetables
Fresh fruits and vegetables are a great source of daily nutrients such as vitamins, minerals, and antioxidants. The drying process, however, may strip some of these. Dried fruits and veggies also have a higher concentration of sulfites, which can impact lung health. To protect one’s respiratory health, always opt for fresh fruits and vegetables.

Cruciferous vegetables
While vegetables are a rich source of nutrients, some of them, such as broccoli and cauliflower, may increase the risk of gas and bloating. This may worsen symptoms and make breathing difficult for those with chronic lung conditions such as MAC lung disease and asthma. If one experiences these changes, limiting consumption of cruciferous vegetables may help.

Vinegar
Vinegar-rich foods generally undergo a fermentation process. Due to this, they contain high levels of sulfites, which may worsen symptoms of MAC lung disease. Some foods with high amounts of vinegar include sauces and salad dressings, marinades, and pickled fruits and vegetables. As a precautionary measure, one must be mindful and practice portion control when consuming these products.

Shellfish
Shellfish like shrimp, lobster, and crab are a rich source of protein, but they also contain high levels of purines. As purines break down in the body, they produce uric acid. This may lead to inflammation and cause breathing difficulties. Shellfish is also one of the most common allergens, which can lead to a severe reaction called anaphylaxis. An anaphylactic shock can cause swelling of the airways, breathing difficulties, and reduced blood pressure levels. Those living with lung disease must be cautious about their shellfish consumption or switch to alternative protein sources such as chicken, turkey, and salmon.

Chronic lung conditions such as MAC lung disease can be difficult to manage. To maintain lung health, one must refrain from indulging in inflammatory foods. Instead, opt for foods such as beets, pumpkins, tomatoes, leafy greens, apples, berries, and high-fiber foods, which may improve lung function and oxygen intake.

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.

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.
