Top 10 Decreased Sweating Causes

  1. 1.Viral (Rotavirus) Infection

    Rotavirus is a virus that causes an infection of the gut, known as gastroenteritis. Symptoms include diarrhea, vomiting and fever. When the diarrhea and/or vomiting is severe, dehydration can occur. Symptoms of dehydration include a dry mouth, dizziness, urinating less frequently and dark urine.

    You can safely treat this condition at home. Make sure you drink plenty of water and fluids to replace what is lost with diarrhea. Eat as normally as possible. If symptoms of dehydration occur, or you are unable to keep down any liquids, seek care at your primary care physician or an urgent care.

    A small bowel obstruction is most often caused by adhesions after surgery, which make it difficult or impossible for food and fluid to pass through the bowel. This causes a blockage. Small bowel obstructions often cause nausea, vomiting, abdominal pain, and constipation.

    This condition requires hospitalization. Treatment depends on the severity of the obstruction but surgery is likely.

  6. 6.Hypertrophic Cardiomyopathy

    Hypertrophic cardiomyopathy (HCM) is a disease in which the heart muscle (myocardium) becomes abnormally thick (hypertrophied). This happens sometimes as a result of long-term elevated blood pressure, and sometimes without any particular reason. The thickened heart muscle can make it harder for the heart to pump blood.

    You should visit your primary care physician. Cardiomyopathy is usually treated with prescription medication to slow down the heart rate and make the heart squeeze less forcefully. In severe cases of cardiomyopathy, an operation called myectomy is performed to remove a segment of thickened muscle from the wall dividing the right and left ventricle (the septum).

    Top Symptoms:
    fatigue, shortness of breath, dizziness, racing heart beat, shortness of breath on exertion
    Urgency:

  7. 7.Low Blood Sodium

    Hyponatremia is a deficiency in sodium. Sodium is one of the most important nutrients in the body, needed for nerves to conduct signals, muscles to contract, and blood pressure to be maintained at safe levels, etc. A deficiency in sodium can cause severe, widespread symptoms.

    You need to seek care immediately. A walk-in clinic will likely be able to help bring your sodium levels back up to normal levels, safely.

  8. 8.Heart Attack in a Woman

    Most heart attacks happen when a clot in the coronary artery blocks the supply of blood and oxygen to the heart. Often this leads to an irregular heartbeat - called an arrhythmia - that causes a severe decrease in the pumping function of the heart.

    You should call 911.
