what causes tightening in the stomach
Abdominal tightening is obvious and it can be persistent in the last few months. The growing uterus and the babyâs movements can both cause the feeling of tightness in the stomach. Weight gain during pregnancy is also associated with tightening of abdomen. The fat deposited under the skin stretches your abdominal wall and causes tightening. Gastric problems are also frequent in late pregnancy that can cause the stomach to feel tighter. However, if the tightening is more pronounced and does not go away, it could be a sign of preterm or even full term labor.
