The main reason for feeling bloated during your period is hormonal fluctuations, particularly changes in estrogen and progesterone levels. These hormones can cause your body to retain water and salt, leading to a swollen, heavy feeling in the abdomen. Progesterone can also slow down your digestive system, causing gas buildup and bloating. Additionally, factors such as increased salt intake, cravings for sugary foods, and intestinal sensitivity during menstruation can worsen bloating. Specifically:

• Estrogen and progesterone fluctuations cause water retention, swelling cells with extra fluid.
• Progesterone slows digestion and bowel movement, causing gas accumulation.
• Increased cravings for salty and sugary foods before periods lead to more fluid retention.
• Intestinal sensitivity can cause gas, constipation, or diarrhea, intensifying bloating feelings.

To reduce period bloating, drinking plenty of water, reducing salt intake, avoiding processed foods, and managing diet by using spices instead of salt can help. Exercise and lifestyle changes may also relieve symptoms. These hormonal and digestive changes typically result in bloating about a week before and during the period, and the bloating usually subsides a few days after the period starts.
