    8 Causes of Night Sweats

    Doctors in primary care fields often hear their patients complain of night sweats. Night sweats refer to any excess sweating occurring during the night.

    However, if your bedroom is unusually hot or you are using too many bedclothes, you may begin to sweat during sleep--and this is normal.

    In order to distinguish night sweats that arise from medical causes from those that occur because one’s surroundings are too warm, doctors generally refer to true night sweats as severe hot flashes occurring at night that can drench sleepwear and sheets, which are not related to an overheated environment.

    In one study of 2267 patients visiting a primary care physician, 41% reported experiencing night sweats during the previous month, so the perception of excessive sweating at night is fairly common.

    It is important to note that flushing (a warmth and redness of the face or trunk) may also be hard to distinguish from true night sweats.

    There are many different causes of night sweats. To determine what is causing night sweats in a particular individual, a doctor must obtain a detailed medical history and order tests to decide if an underlying medical condition is responsible for the night sweats. Some of the known conditions that can cause night sweats are:

    Menopause – The hot flashes that accompany the menopausal transition can occur at night and cause sweating. This is a very common cause of night sweats in perimenopausal women.

    Idiopathic hyperhidrosis – Idiopathic hyperhidrosis is a condition in which the body chronically produces too much sweat without any identifiable medical cause.
    Infections – Classically, tuberculosis is the infection most commonly associated with night sweats.

    However, bacterial infections, such as endocarditis (inflammation of the heart valves), osteomyelitis (inflammation within the bones), and abscesses all may result in night sweats. Night sweats are also a symptom of AIDS virus (HIV) infection.

    Cancers – Night sweats are an early symptom of some cancers. The most common type of cancer associated with night sweats is lymphoma. However, people who have an undiagnosed cancer frequently have other symptoms as well, such as unexplained weight loss and fevers.

    Medications – Taking certain medications can lead to night sweats. In cases without other physical symptoms or signs of tumor or infection, medications are often determined to be the cause of night sweats. Antidepressant medications are a common type of medication that can lead to night sweats. All types of antidepressants can cause night sweats as a side effect, with a range in incidence from 8 to 22% of persons taking antidepressant drugs.

    Other psychiatric drugs have also been associated with night sweats. Medicines taken to lower fever such as aspirin and acetaminophen can sometimes lead to sweating.

    Other types of drugs can cause flushing, which, as mentioned above, may be confused with night sweats. Some of the many drugs that can cause flushing include:
    niacin (taken in the higher doses used for lipid disorders),
    nitroglycerine, and
    sildenafil (Viagra).
    Many other drugs not mentioned above, including cortisone medications such as prednisone and prednisolone, may also be associated with flushing or night sweats.

    Hypoglycemia – Sometimes low blood glucose can cause sweating. People who are taking insulin or oral anti-diabetic medications may experience hypoglycemia at night that is accompanied by sweating.

    Hormone disorders - Sweating or flushing can be seen with several hormone disorders, including pheochromocytoma, carcinoid syndrome, and hyperthyroidism.

    Neurologic conditions – Uncommonly, neurologic conditions including autonomic dysreflexia, post-traumatic syringomyelia, stroke, and autonomic neuropathy may cause increased sweating and possibly lead to night sweats.

    Interesting that AIDS is noted as a cause of "nightsweats"..

    The immune system dysfunction that many of us suffer from is almost identical to that of AIDS patients (See "Osler's Web" by Hillary Johnson).

    Sweating whenever you are standing still can also be a symptom of "orthostatic intolerance" or "low blood volume" (see Cheney's research).

    I suffered from CONSTANT sweating with any exertion or standing still for 14 years, until I started the Xyrem.

    Within a couple of months of starting it, the sweating was greatly diminished, and now it's completely gone. So is the orthostatic intolerance, and my immune system is working well for the first time since I got sick.

    Your therapist says
    it was all a mistake.
    A product of the Prozac
    and your co-dependent ways.
    So, who's your enabler these days?
