Hello doctor,

I have found low lying placenta about my 21 weeks pregnancy, though I did not have bleeding yet. Can I do long travel by air after 1 or 1.5 months later for emergency purposes? My reports are attached. I found constipation a little bit, no bleeding at all till now. My TSH is 2.83. What should I eat for being healthy? What should I do to avoid for my low lying placenta? What should I eat for constipation problem? Is there any natural way, or should I take medications?



Welcome to

I went through your query. It is quite common to see a low-lying placenta at 21 weeks. Do not worry. Placentas migrate to the upper uterine segment in later gestational age. I would recommend you to do another ultrasound at 28-30 weeks to see the placental localization. However, it is not advisable to do air travel in the coming 1.5 months as it is low lying. You could do an ultrasound at 28-30 weeks. If the placenta is not low lying, you can do air travel if required on an emergency basis. Regarding constipation in pregnancy, you can take Movicol two sachets at night time. Drink plenty of water, at least 0.6 gallon per day. Eat foods rich in fiber like prunes, apples, pear, green leafy vegetables, spinach, etc. Try to walk for 15-20 minutes every day. Regarding thyroid hormone levels, continue to take thyroid supplements as thyroid levels are a bit high. Avoid overeating cabbage and cauliflower.
