###Human: Is it advisable to have long flight travel during pregnancy? ###Assistant: Hi. Please ensure that you are not a high-risk pregnancy as per your obstetrician before traveling. Air travel is allowed during pregnancy (except high-risk cases like threatened pregnancy, high BP, diabetic, twins), just keep the following things in mind especially for more than four hours stretch flight. Drink plenty of water to keep you hydrated. Move around in the flight to keep the blood flowing through your legs, otherwise, you may develop foot swelling and cramps. Do some stretching exercises of legs while even sitting and watching the movies every 30 minutes. Prefer a break journey flight, so you do not feel nauseated due to closed flight space. Maintain sleep pattern same to prevent jet lag and sleeplessness. Take your usual medicines and an extra dose of antacid and anti-emetic. Also, travel with all pregnancy-related documents, and have a fit to fly certificate from your obstetrician, as many flights ask for it in advanced pregnancy. Have light and frequent meals, keep some food stacked in your purse, for frequent snacking, rather than hostess serving you at fixed times. Wear graduated compression stockings in flight long haul flights. Enjoy your journey without worrying much.
