This is my 5th month, 20th week and 1st pregnancy. In the first trimster, I had nausea feeling during the whole day but had slight vomiting 5 or 6 times only during the whole trimster. But I've been suffering from acidity and gas problem since before my pregnancy also. But this has increased now manifolds during pregnancy. I also have sour or bitter taste in my mouth for most of the time. After about 1.5 to 2 hrs of having food, I feel sever acidity. And if I do not have food for another an hout or so, it develops into severe gas. My stomach gets bloated and feels very tight. Eating fruits, biscuits help only temporarily unless I have regular food (chapatti, vegetable, bread etc) which I've 3 times a day.
After having food, acidity and gas subsides for few hours. But my heart starts racing very fast and I feel very tired for around 1 to 2 hours. After that it gets normal. Lying down also does not help much. Since I'm working, so in the afternoon there is no option of taking rest. Also I've long working hours, about 9 to 10 hrs. Also I've found that having rice in my meals also increases my heart rate a lot, so I've stopped having it.

Kindly suggest me what to do about my acidity and gas problem and fast heart beat after meals?

Thanks,

do not eat with speed. Take time to chew your meal or fruits, otherwise you can get terrible acidity.
Archie Archie replied. Dear ng,
In some cases avoiding spices or reducing them has helped a lot. Try to eat food that's less or non-spicy.
If you are in USA then you can eat TUMS they are great to provide relief from heartburn.
If you live elsewhere then ask your Dr. to prescribe safe antiacid.
Do not lye down on bed before you have completed 2 hours of your meal.
Do not work under stress. Try to take things easy at your work.

Although looks OK to me, I suggest you to buy a blood pressure measuring device, they are handy and cheaper in USA. Keep your blood pressure measured everytime you feel high pulse rate. Or bring this to your Drs. attention on your next visit.

Good luck
Archie
