It is a common thing, people complain to their doctors: the night sweats. It means people are sweating over night more than usual. The night sweats differ from those we may encounter due to overheating our bedroom or wearing too much bedclothes. Night sweats are severe hot flashes occurring at night that can drench your clothes and sheets and that are not related to an overheated environment.
There are many different causes of night sweats. Doctors are not sure if there is only one trigger behind it, or are there multiple issues. It can be sometimes difficult to diagnose the right cause, but luckily we recognize some of the conditions that cause night sweating:
Menopause is accompanied with hot flashes which can occur in the night.
- Idiopathic hyperhidrosis
This is a condition in which the body chronically produces too much sweat without any identifiable medical cause.
- Various infections
Tuberculosis is the infection most commonly associated with night sweats. But bacterial infections, such as endocarditis (inflammation of the heart valves), osteomyelitis (inflammation in the bones), and abscesses can cause night sweats. Night sweats are also a symptom of HIV infection.
Night sweats can be an early symptom of some cancers. The most common type of cancer associated with night sweats is lymphoma. Still, people with undiagnosed cancer will surely experience additional symptoms, i.e. unexplained weight loss and fevers.
Even some medications can cause night sweats. Antidepressant drugs can lead to this condition. Aspirin and acetaminophen can also lead to this condition.
Hypoglycemia of low blood sugar can cause sweating as well. People who take insulin may experience this condition.
- Hormone disorders
Various hormone disorders can trigger night sweating, such as pheochromocytoma, carcinoid syndrome, and hyperthyroidism.
- Neurological conditions
Even some neurological issues are connected to night sweating: autonomic dysreflexia, posttraumatic syringomyelia, stroke, and autonomic neuropathy.
