Hi and welcome to HCM In first trimester decreased appetite is common. Many pregnant women in first trimester suffer from nausea, morning sickness and vomiting which makes them difficult to eat and also if anemia is their (that is less haemoglobin) it also suppresses appetite If you have nausea and vomiting, follow these instructions 1.Eat little and often to prevent heartburn and nausea. An empty stomach can increase nausea. Keep blood sugars steady. Try eating small amounts of bland, dry food throughout the day. 2.avoid rich, spicy, acidic or fried foods, and eat less fat in general as they tend to irritate your stomach lining resulting in the production of more gastric acid 3.Do not lie down after a meal. If you move about a bit, you re less likely to throw up the food 4.Try drinking between meals if you re finding it hard to keep fluids down, and limit drinks during meals. Be sure to drink regularly 5.Have a spoon of diluted ginger juice mixed with honey every morning. Ginger is known to settle stomachs and help nausea. However, ginger should be used in moderation and with care – it doesn t help everyone. 6.Vitamin B6 (pyridoxine) or a pregnancy multivitamin may reduce pregnancy sickness and also some drugs like doxinate can control vomiting, but do take this medication under your doctor care. But nausea and vomiting will come down by second trimester and also your appetite will increase Regards Dr Santosh
