hello.. thanks for trusting the healthcare magic doctors for ur health related queries.. I guess ur concern is about..is the weight gain a sign of bloating..right. my answer is...NO. weight gain is not at all the sign of bloating. let us discuss about the sign n symptoms u have. as u told that u had gain weight n having difficulty in sleeping. so u might be have PCOS (polycystic ovarian syndrome). in this patients usually have irregular menses, weight gain n difficulty in conceiving. few patients having difficulty in sleeping, excessive hair growth in unusual area of the body etc. but didn t give info regarding ur menses whether it is regular or not. so it is difficult for me to comment on this. lastly i want to say that weight gain is not the sign of bloating. with the above discussion u can try out my suggestions- 1. first u should reduce ur weight because it may pose difficulty in conceiving because it causes hormonal imbalance which causes irregular menses n patients having difficulty in conceiving.so try to change ur food habbit in a way to reduce ur weight. 2. for more details u can visit ur nearby gynecologist n feel free to ask about ur concern. he/she can help u. 3. try to do coitus during fertile period(it is from 10th to 16th day of menses during this period chances of getting pregnant is high. so do more coitus during this period.u may get better results. 4. DON T WORRY about the miscarriage u had in past. it doesn t effect ur future chances of getting pregnant. 5. if u r still in hurry then visit nearby infertility specialist. he/she can help u.
