Mucus in stool is not a sign to worry about. You may improve your lifestyle and undertake preliminary measures to reduce the excess secretion of mucus in stool.

When stool has an excess amount of visible mucus during pregnancy, it may be due to health conditions, such as (10) (11) :

  • Irritable bowel syndrome
  • Ulcerative colitis
  • Crohn’s disease

One may take note of the symptoms and consult a doctor in the following cases:

  • There is an excess amount of mucus in the stool
  • Blood or pus in the stool
  • Pain while passing stool
  • Having stomach pain, cramping, or bloating
  • Sudden changes in stool frequency, consistency, or color

1. Can probiotics cause mucus in stool?

Research indicates that probiotics may alter the composition and volume of stool, causing gassiness and increased mucus secretion in stools. If you notice these symptoms after consuming probiotics during pregnancy, you should talk to your gynecologist or nutritionist (16).

2. Can anxiety cause mucus in stool?

Anxiety may increase mucus secretion in stool in some individuals (13). However, the underlying reason is not known, and it may not happen to everyone.

3. Can mucus in stool during pregnancy be a sign of preterm labor?

The mucus in the stool during pregnancy is not linked to preterm labor. However, if you have any concerns or are experiencing other symptoms, you must consult your doctor for diagnosis and treatment (17).

4. Does mucus in the stool during pregnancy affect the baby’s health?

Dr. Kubanych Takyrbashev, a doctor of internal medicine and anesthesiology from Minneapolis, Minnesota, says, “Mucus in the stool usually doesn’t harm the baby’s health. However, if you experience other symptoms such as blood in the stool, severe abdominal pain, or changes in bowel habits, it is important to consult your healthcare provider to ensure your and your baby’s safety.”

Mucus in stool during pregnancy is usually normal. It may happen due to dehydration, hormonal changes, or food allergies. Understanding your body and making lifestyle changes such as drinking more water, avoiding allergic food, or eating healthy helps keep the problems at bay. However, do not ignore symptoms like pain when passing stool or the presence of pus or blood in stool during pregnancy, as these may indicate more serious conditions such as irritable bowel syndrome or Crohn’s disease. In such cases, it is necessary to consult a doctor.
