Night Sweats

Also called: Nocturnal Hyperhidrosis

Night sweats, or nocturnal hyperhidrosis, are episodes of excessive sweating during sleep that drench clothing and bedding. They are a significant systemic symptom indicating an underlying condition is causing a widespread inflammatory or metabolic response. In the context of colorectal disease, night sweats are a major red flag for a serious infection, most notably an intra-abdominal or pelvic abscess resulting from conditions like diverticulitis or an anastomotic leak. They can also be a constitutional symptom of advanced malignancy or a severe flare of inflammatory bowel disease. A workup, typically including a CT scan, is essential to find the cause.

Frequently asked questions

Could my night sweats be from menopause?
Yes, night sweats are a classic symptom of menopause. However, in a medical evaluation, it is important not to assume this is the cause, especially if the sweats are new, drenching, or associated with other symptoms like weight loss or fever. A thorough workup is still necessary to rule out other medical causes.

Are night sweats always a sign of cancer?
No. While they can be a symptom of some cancers, night sweats are more commonly caused by infections or inflammatory conditions. However, because they can be a sign of cancer, they should always be taken seriously and evaluated by a doctor.
