MAC lung disease – 8 common signs and management options

MAC lung disease – 8 common signs and management options

MAC is a group of pathogens known as Mycobacterium Avium Complex or nontuberculous mycobacteria (NTM) found in the environment. They infect the lungs and lead to MAC lung disease, which is of two types: one type causes the development of nodules in the lungs and is called nodular disease, and the second type affects the cavities in the upper parts of the lung and is called upper lobe cavitary disease.

Here are some of the common signs of MAC lung disease and how to manage them:

Common signs of MAC lung disease
The signs of MAC lung disease differ on a case-to-case basis. In most cases, the symptoms are generally nonspecific. Also, some may experience mild symptoms, or the signs may be nonexistent. As a result, there is often a delay in diagnosis and treatment. Some people have mild or unnoticeable symptoms. When the symptoms do occur, one may experience the following:

  • Disruption in lung function
    When the NTM pathogens accumulate in the lungs’ cavities, they can create a hole in the lung tissue. This can cause pain in the chest. In addition, a person may experience persistent wheezing and coughing. In some cases, the coughing is accompanied by bouts of breathlessness. There might be blood or mucus expelled during a coughing fit.
  • Severe fatigue
    As MAC infection progresses, it can make a person feel severe fatigue over time. One may feel like they have been drained of all energy. This generally happens due to breathlessness and severe coughing. There can be low oxygen levels, which may make one feel extremely tired with enough rest. Sometimes, the exhaustion is so severe that a person cannot carry out daily activities.
  • Stomach issues
    One experiences stomach issues when a person has a disseminated MAC infection. This happens when the infection spreads to other body parts beyond the lung. As a result, one may experience frequent bouts of diarrhea and constant abdomen pain. Also, there can be a loss of appetite accompanied by a decreasing sense of hunger.
  • Swollen lymph nodes
    The job of lymph nodes is to transport white blood cells all over the body. These lymph nodes swell up when the body tries to fight germs and infections. In the case of MAC lung disease, the lymph nodes in the neck become swollen. This is known as cervical lymphadenitis. This symptom is rarely observed in adults but is common in young kids.
  • Flu-like symptoms
    Most infections caused by bacteria, viruses, and other germs have similar symptoms. So, MAC lung disease may also make one experience flu-like symptoms. There can be a high fever as the body temperature increases, with an overactive immune system fighting off the infection. For the same reason, one may also experience muscle aches, body pain, and chills.
  • Night sweats
    Some people with MAC infections experience severe sweating during the night compared to the daytime. This generally happens when the infection causes a high-grade fever. Sometimes, sweating is so extreme that one may wake up drenched in the middle of the night.
  • Anemia
    A significant disseminated MAC lung disease symptom is a low red blood cell count. One of the reasons why this happens is that the body finds it difficult to use iron to create sufficient levels of red blood cells when there are recurring and ongoing infections due to germs such as NTM. This triggers anemia.
  • Skin issues
    Due to MAC lung disease, a person may experience several skin problems. For instance, sores might develop on the lower limbs, feet, and other body parts. In addition, the skin around the sores may be painful and appear reddish or purplish. In severe cases, the sores turn into ulcers or open wounds. This generally happens in the case of untreated disseminated MAC lung disease.

How to manage the signs and symptoms of MAC lung disease
A pulmonary specialist or infectious disease expert will prescribe specific treatment options to manage the signs of MAC lung disease. These options are devised based on one’s overall health and the severity of the symptoms. In addition, the type of MAC infection is also taken into consideration. Doctors usually monitor symptoms before starting the treatment. Here are some ways to manage and treat MAC lung disease:

  • Airway clearance therapies
    With this therapy, sputum and bacteria are cleared from the lungs. These usually involve different types of breathing treatments.
  • Surgery
    If the symptoms are too severe to be treated, surgery is done to remove a part of the infected lung.
  • Moderate-intensity exercises
    These involve chest and breathing techniques, chest percussions to loosen mucus, controlled coughing, and postural drainage or positions to drain mucus out of the lungs. These are done to clear the airways under the guidance of a respiratory therapist.
  • Balanced meals
    A nutrition specialist can help draw up meal plans that can aid in fighting off the infection. These meal plans include foods that relieve symptoms, strengthen the immune system, and help with general well-being.

4 healthy foods for nursing mothers

Mothers who have recently delivered babies don't have sufficient nutrition due to the loss of blood and lactation. As a result, they have to carefully choose foods that are rich in calcium, carbohydrate, unsaturated fat, iron, folic acid, protein, and vitamins B6, B12, C, and D. Thankfully, healthy foods and supplements can help them regain strength and supply breastmilk to their newborns. The top four superfoods that can help nursing mothers include: Bananas Bananas are less expensive, available throughout the year, and considered a superfood for nursing moms. They are rich in nutrients, healthy carbs, vitamin B, antioxidants, and phytonutrients. Bananas are also abundant in potassium, calcium, and pectin, a source of energy. Experts claim that having a banana every day can help moms regain the energy they need to take care of the baby and breastfeed. Potassium is crucial for maintaining fluid balance in the mother's body and aids in the rampant transmission of nerve impulses.  Bananas can also aid in regulating blood pressure. It can prevent constipation, aid in regular bowel movements, and promote healthy gut bacteria. These fruits can provide about 1/4th of the vitamin B6 required for nursing moms, which is crucial for hemoglobin production and fighting antibodies. However, avoid bananas if you have allergies, a bout of cough and cold, or diabetes. Mothers can eat bananas after any meal or even add them to smoothies or pancakes as part of a meal. Fatty fish Fatty fish are naturally rich in vitamin B12, omega-3 fatty acids, and vitamin D. Fish like salmon and sardines are one of the few food sources of vitamin D, which is essential for mothers and their infants. A deficiency of vitamin D in infants, though uncommon now, can lead to weak and deformed bones. These fish also contain DHA, a type of omega-3 fatty acid essential for an infant's brain and heart development. DHA can be naturally found in breast milk if a mother eats fatty fish, eggs, or red meat. Omega-3 acids can also help in preventing postpartum depression. Mothers can choose from freshly caught fish, buy from verified farms, or use canned salmon. However, ensure that you have salmon or sardines twice a week to get its benefits and increase the production of breastmilk production. Homemade stock Soups and broths are wholesome and satisfying meals for nursing mothers. The most significant advantage of broths or soups is you can make large quantities and freeze them. The first three months can be hectic for new moms, which is why broths are perfect. They are nutritious, time savers, and can instantly replenish nutrients and strength. Mothers can use the bones and cartilage of chicken or lamb for meat broths. However, slow-cook them as the soup will have time to absorb all the nutrients and minerals from the meat and bones.  On the other hand, vegetarian mothers can make soups and broths of various vegetables and lentils. Bell pepper, carrots, celery stalks, french beans, lentils, mung, cottage cheese, and peas are ideal ingredients for vegetarian soups. Broths and soups can also help deal with postpartum depression and help regain bone density. It can also help reduce joint pain and strengthen joints right after childbirth. Leafy green vegetables It is widely known that green leafy vegetables contain multiple nutrients like vitamin A, C, E, and K, fiber, minerals, calcium, and antioxidants. Spinach has a high concentration of phytoestrogens and iron. When a nursing mom increases the intake of spinach, it raises the estrogen level and helps stimulate milk production. Phytoestrogens also help in regulating and reducing cholesterol and blood sugar levels. They are low on calories; hence, you do not have to worry about gaining weight. One serving of green leafy vegetables daily is the recommended quantity for nursing moms.  Mothers can also eat broccoli and Swiss Chard, which are high in calcium and iron. The daily calcium requirement for nursing moms is about 1,300 milligrams a day. Kale or collard greens also can supply about 20% of the daily calcium requirement. Moms can also have milk and yogurt to ensure they receive the necessary supply of calcium. They can add greens to salads, smoothies, soups, or casseroles. Cigna breast pump Cigna is a global health service company that offers health, pharmacy, dental and supplemental insurance, and Medicare plans. You can get 100% of Cigna's insurance for hospital-grade and standard electric breast pumps with a prescription from your physician, midwife, or nurse practitioner. Cigna also covers the cost of renting a heavy-duty hospital-grade breast pump if a standard breast pump fails. Elvie Free Elvie, one of the brands covered by Cigna with a doctor's prescription, has introduced a revolutionary, silent wearable breast pump that women can discretely fit in their clothes. It is a wireless breast pump that can be operated through a smartphone. This easy-to-use pump can be used confidently and without any hassle. Since it is silent, it can be used anywhere without any disturbance or the need for privacy. Moreover, there are no tubes or pipes. It consists of five easy-to-assemble and clean components that make pumping clean and safe. If you're a new mother who wants to try out breast pumps, give this a try after consulting a doctor.

The 5 stages of Huntington’s disease explained

Huntington's disease is a genetic, neurodegenerative condition characterized by emotional, cognitive, and motor symptoms. The course of the disease involves a gradual development of involuntary jerking muscle movements and a progressive decline in memory and cognitive function. It shows symptoms such as uncontrolled movements and mental instability. Huntington's disease (HD) is a genetic disorder inherited from a parent and is commonly divided into five stages of disease progression. So, let's learn more about each stage. Stage 1: Preclinical stage People in the initial stage of Huntington's disease may develop mild symptoms. While they may exhibit signs of a neurodegenerative disorder, the doctor might not diagnose the individual with Huntington's disease. The symptoms of HD usually begin between 40 and 60 years of life. However, it may also appear as two years of age or as late as 80 years. In the early stages, damage to brain cells may cause symptoms such as: Involuntary twitching in the toes, fingers, or face Poor coordination May struggle to concentrate or solve problems Irritability Loss of inhibitions Depression Issues with complex movements Once these symptoms appear, a patient is diagnosed to be in the active stages of HD. It may take about eight years to pass from this stage to the next. The individual can usually carry out tasks at home or work without assistance. For example, the person might be able to drive, bathe, and drink. However, experts may recommend reducing the work and hours carried out each day. Stage 2: Early intermediate stage By this stage, one usually exhibits clear signs of the disease as they become more apparent and may interfere with the individual's daily life. The individual may also develop emotional and behavioral issues, which might cause strain on work and family relationships. Furthermore, the symptoms experienced in the early intermediate stage are similar to those of the previous stage and may become more noticeable. Based on the individual, stage 2 could last three to thirteen years. The second stage is a comfortable time to discuss important topics with the patient, such as support systems, health and Huntington's disease care plan, and legal and financial plans. Stage 3: Late intermediate stage Patients who reach the third stage of Huntington's disease may be unable to work any longer. The disease may have affected them to the extent that they could require assistance with daily tasks. The third stage usually goes on for about five to sixteen years, and one may notice signs such as: Wright issues Trouble with walking Difficulty with memory A severe problem with involuntary movements or twitches A restricted ability to perform motor tasks Depression Mood swings Falling frequently Stage 4: Early advanced stage The time it takes to reach this stage may differ from one person to the next. Someone with Huntington's disease usually enters the early advanced stage about ten years after the onset, but it could also range between nine and twenty-one years. One may require advanced care when approaching this stage, especially considering household responsibilities, personal matters, and finances. The patient’s caretakers, such as family members or close peers, may also have to determine if the individual with Huntington's disease should live at home or move to a facility where they can be cared for. Patients may also exhibit new symptoms in the early advanced stage, such as: Rigidity Apathy Abnormally slow movements Excessive loss of cognitive function Severe challenges regarding voluntary movements Stage 5: Advanced stage The fifth and final stage is when the disease becomes more severe, and the individual might require round-the-clock care. The person might be immobile, unable to communicate, and find it extremely tedious to perform essential motor functions, such as swallowing. In the advanced stage, the patient becomes entirely dependent on others to complete anything. They may also fall ill regularly because of infections or injuries. The available treatments for Huntington's disease aim to slow its progression and improve the patient's quality of life. Experts may recommend prescriptions to manage various symptoms of the disorder. They may also indicate therapies, such as speech and physical therapy, to help one cope with HD. The patient's family could also look into support services, such as nonprofit agencies, to provide caregiver education and support groups to help the patient learn more about the condition.

8 effective remedies for nasal polyps

8 effective remedies for nasal polyps

Nasal polyps are tiny tear-shaped growths in the nose and sinuses, usually brought on by asthma, infection, allergies, or other kinds of inflammation. These polyps are usually painless and non-cancerous, however, they can be big enough to cause itchiness, breathing difficulties, sneezing, and running nose. Doctors usually prescribe nasal sprays that can relieve the symptoms and get rid of the polyps. However, one can also try a few natural remedies to deal with the condition: Neti pot (or nasal irrigation) Neti pot is a popular and convenient nasal irrigation device. All one has to do is fill this container with saline solution or add 1–2 tsp salt to distilled water or boiled (and then cooled) tap water. Then, one would have to lean over a washbasin or a sink and tilt their head sideways so that the liquid does not flow back into the mouth. One would have to breathe through the mouth, insert the spout into the upper nostril and allow the fluid to drain from the lower nostril. Then the nostrils will have to be cleaned by blowing the nose to remove mucus and dirt. This process should be repeated through the other nostril. The goal is to loosen and clear the mucus and debris like dust or pollen from the nasal cavity.
