Some women may have sweating during the day while others at night. A few may sweat during the day and night too. Below are some of the common reasons why you could sweat during pregnancy:

  1. Increased metabolism: Your body needs more energy to support your baby, thus resulting in an increased rate of metabolism. This, in turn, activates your sweat glands and as a result, you will sweat more.
  1. Hyperthyroidism: If you have hyperthyroidism during pregnancy, you might experience excessive sweating anytime throughout the day and night. The condition could extend after the delivery as well (3).
  1. Gestational diabetes: If you are diagnosed with gestational diabetes, you may notice excessive sweating. Sweating could especially increase when you have hypoglycemia or low blood sugar level (4).
  1. Medications: Taking certain medicines such as acetaminophen or aspirin to reduce glucose level or fever, or antipyretics and antihypertensives could result in excessive sweating (5).
  1. Increased blood flow: Blood flow to the skin increases during pregnancy, which makes your body warmer and results in increased sweating (6).
  1. Infections: A urinary tract infection during pregnancy may cause sweating too (7).
  1. High levels of progesterone: During pregnancy, the levels of the hormone progesterone go up. This increases body temperature, which results in sweating (8).
  1. Others: Eating spicy food or consuming caffeinated beverages, exhausting your body with too many physical activities, or intense exercise could be some other reasons for sweating more during pregnancy.

Irrespective of the cause of sweating, it is possible to manage it and avoid the discomfort.
