Potential complications related to poor intake during pregnancy
Undernutrition can lead to many pregnancy-related complications, including poor fetal growth, low birth weight, and maternal weight loss. It’s also associated with lower mental function and behavioral problems in children (29, 30, 31).
To maintain a healthy pregnancy, both macronutrients and micronutrients are necessary.
Anemia, abnormal fetal growth, and preterm birth are risks for pregnant people with chronically poor appetites (32, 33).
You might lose your appetite or find some foods to be unappealing as your body adjusts to pregnancy. Even when you’re starving, it’s not always easy to force yourself to eat.
Remember that a lack of appetite is a fairly common symptom that is frequently accompanied by other symptoms like nausea and vomiting. It’s normal for your appetite to change from time to time.
Eat small portions of bland, basic foods that are filling, high in nutrients, and easy on your stomach if you lose your appetite but still feel hungry.
Consult a doctor if you experience persistent or long-lasting loss of appetite.

Do not be alarmed if you experience appetite loss while pregnant; this is a typical pregnancy symptom. Here are the causes and remedies so you can continue to put on weight and consume the nutrition you require.
Pregnancy is that one special time in your adult life when gaining weight is encouraged and eating every two hours is encouraged (lucky you!). You may have always associated pregnancy with a voracious appetite for everything from pepperoni pizza to ice cream and pickles.
But as soon as you start stocking your refrigerator with nutritious foods (and occasionally those cookies you’re craving), morning sickness and loss of appetite strike, making you turn your nose up at the sight and smell of your favorite foods.
The main indicator that you’re eating enough to meet your baby’s needs is gaining enough weight during pregnancy. The majority of normal-weight women should try to gain between 25 and 35 pounds, depending on their pre-pregnancy weight.
It’s typical to only gain one to four pounds (or occasionally even lose weight) during the first trimester, when morning sickness (often referred to as all-day sickness) is at its worst. That’s okay. Since your fetus is so small at this point and has fewer nutritional needs, as long as you’re taking your prenatal vitamin, you and your unborn child should be covered.

It is advised to gain one pound per week after the first trimester. Consult your doctor if your appetite is still absent by the beginning of your second trimester or if you aren’t gaining the recommended amount of weight in your third trimester.
Still worried? Don’t be. There will be good days and bad days; what matters is the overall picture. The good news is that most women can control appetite loss with a few simple techniques.
