Nocturnal Perianal Sweating Causes

There are no research papers that directly address the causes of nocturnal perianal sweating. However, studies on night sweats and hyperhidrosis provide some insights into possible causes of excessive sweating at night, which may be related to nocturnal perianal sweating.

• Possible causes of night sweats include:
  • Hormonal changes, such as menopause and hyperthyroidism 1, 2
  • Sleep disorders, such as obstructive sleep apnea and insomnia 3
  • Gastroesophageal reflux disease and other gastrointestinal conditions 1, 4
  • Medications and substances, such as antihypertensives and alcohol 4
• The mechanisms underlying nocturnal hyperhidrosis, which may be related to nocturnal perianal sweating, include:
  • Sympathetic overactivity 3
  • Orexin deficiency in the case of narcolepsy type 1 3
• It is essential to note that the causes of night sweats and hyperhidrosis can be diverse and may not be directly applicable to nocturnal perianal sweating. Further research is needed to understand the specific causes of nocturnal perianal sweating.
