A Swollen Belly Every Time Your Period Approaches? Managing PMS Abdominal Distension with Korean Medicine

The abdominal distension and discomfort that appear before menstruation are recognized in modern medicine as common symptoms of premenstrual syndrome. During this phase, the balance between the sex hormones estrogen and progesterone shifts sharply, influencing delicate systems throughout the body. Progesterone tends to slow intestinal motility, specifically peristalsis. Much like highway traffic slowing when a sudden speed limit is imposed, reduced gut motility causes food to linger longer in the digestive tract, generating excess gas and leaving the abdomen feeling uncomfortably full. At the same time, the body tends to hold on to more fluids. These hormonal shifts affect fluid-regulating hormones such as antidiuretic hormone and aldosterone. As fluids accumulate, swelling can appear not only in the abdomen but throughout the entire body. In addition, the endometrium secretes prostaglandin. While this substance stimulates uterine contractions that cause dysmenorrhea, excessive secretion can also affect the gastrointestinal tract, contributing to abdominal pain, diarrhea, or constipation. The brain and digestive system communicate continuously through the neurological pathway known as the gut-brain axis. Premenstrual hormonal shifts influence neurotransmitters such as serotonin in the brain, which can amplify both mood changes and gut discomfort. High stress or irregular eating habits can aggravate this hormonal imbalance, worsening these symptoms. This calls for looking beyond physical symptoms to reflect on your emotional state and daily habits. The body is intricate, and managing these persistent discomforts requires supporting both gut health and emotional calm while this complex hormonal rhythm unfolds.
