Causes
By Mayo Clinic staffNight sweats are common and usually aren't cause for concern. In some cases, night sweats may be triggered by something as straightforward as too many blankets on your bed or certain medications. Many women have night sweats when they go through menopause. But sometimes night sweats can be caused by a medical disorder. Infection, cancer, problems in your nervous system or in your body's hormone-producing glands (endocrine system) can all trigger night sweats.
Medications that can cause night sweats
Night sweats are a common side effect of many medications, such as:
- Antidepressants
- Antipyrectics — medications that lower your body's temperature
- Hypoglycemic agents — medications that decrease the level of sugar (glucose) in your blood
- Hormone therapy — medications that regulate the amount of hormones in your body
Medical conditions that cause night sweats
Diseases and conditions that can cause night sweats include:
- Autonomic neuropathy (damage to your autonomic nerves)
- Brucellosis (a bacterial infection)
- Carcinoid syndrome (a syndrome resulting from a certain type of cancerous tumor)
- Endocarditis (an infection of your heart lining)
- HIV/AIDS
- Hodgkin's lymphoma (Hodgkin's disease)
- Hyperthyroidism (overactive thyroid)
- Leukemia
- Menopause
- Myelofibrosis (a bone marrow disorder)
- Non-Hodgkin's lymphoma
- Osteomyelitis (a bone infection)
- Pheochromocytoma (a rare adrenal gland tumor)
