Hello dear, The symptoms as mentioned in your post is attributed to accumulation of gas in the stomach. The presence of constipation and the pregnant uterus pressing over the bowels has an additive effect over this. Under such circumstances, you need to regularize your bowel movements first. Symptomatic relief can be obtained with intake of Pantoprazole preparation (to be taken twice a day before meals) & antacid gel (to be taken after meals). They prevent formation of excess acid in the stomach & provide symptomatic relief. And it is also needed that you take certain precautions regarding your diet & lifestyle, such as: 1. Take soft, plain, non-spicy foods. 2. Drink lots of water to maintain adequate hydration. 3. Avoid fast foods, carbonated drinks & gas producing food products like cabbage, etc. 4. Avoid smoking & alcohol. 5. Keep away stress, think positive. If symptoms still persist, kindly consult a Gastroenterologist for proper clinical examination. There is no need to worry, you will be fine. Wishing a good health. Take care.
