Morning sickness, nausea, and vomiting are the main reasons women have less or no appetite during pregnancy in the first trimester. According to the UK National Childbirth Trust (NCT), 50 to 80 percent of expecting mothers experience them early in pregnancy (2). Additionally, sensitivity to strong smells and the development of a metallic taste in the mouth are other reasons for food aversion, leading to appetite reduction. Fluctuation in pregnancy hormone levels (leptiniXA hormone released by the adipose tissue or body fat, leptin’s primary function is to maintain the body weight for the long term. and human chorionic gonadotropin (hCG)) is another possible cause.

Nurul Ali, a mom, shares how morning sickness during pregnancy affected her appetite. She says, “I still remember that very night when I felt the first signs of nausea. My parents had bought me supper, and I just couldn’t get myself out of bed. Strangely, I didn’t feel like I could down any food at the time. Within the next few days, lethargy hit me hard, and my appetite deteriorated… Have to admit, I recalled feeling a small percentage of happiness for the fact that I was having morning sickness because it signified my pregnancy! (i).”

Pre-existing disordered eating can be another reason for a woman not eating enough during pregnancy. Pregnancy and its related discomforts may exacerbate an eating disorder such as anorexia nervosa (intense calorie restriction due to eating very low amounts or exercising too much). Weight gain and changes in body shape may also trigger anorexia. Women with eating disorders may have an increased risk for stillbirth, premature delivery, having low birth weight babies, and difficulty while breastfeeding (3) (4)

Generally, reduced appetite in the first trimester doesn’t affect the health of the mother or the baby. However, in severe cases, it can lead to adverse outcomes. For instance, a mother with hyperemesis gravidarumiXIt is a term used to describe the persistent and extreme form of vomiting and nausea in pregnant women. It can cause dizziness and dehydration. (HG) can experience persistent and severe pregnancy-related nausea and vomiting, leading to a lack of appetite, dehydration, and electrolyte imbalances (5). So, what can you do to ensure that you and your growing fetus get optimum nourishment?

Tips To Meet The Nutritional Needs In The First Trimester

Here are some practical tips to ensure you get the nutrients you need for a healthy pregnancy.

  1. Have small frequent meals: Frequent vomiting or nausea can cause severe food aversion and decreased hunger. If you are facing this issue, don’t force-feed yourself. Instead, break your three big meals (breakfast, lunch, and dinner) into four to five smaller meals and eat at regular intervals. This way, the amount of food you eat in a meal is much less, which helps keep the food down in the stomach. Also, eating smaller portions of food at regular intervals helps keep your blood sugar levels in good control.

Note: If the appetite loss is due to disordered eating, you may try drinking protein shakes when you cannot eat healthy meals or snacks. However, do not use protein shakes to replace meals. Instead, use them to get consistent nourishment (3).

  1. Make healthy choices: Whenever you feel hungry during the day, eat healthy, easily digestible foods, such as bananas, unsweetened yogurts or smoothies, and whole-grain crackers. Eating healthy foods containing plenty of protein, fiber, and other essential nutrients ensures you and your baby get sufficient nourishment.

  1. Stay hydrated: Drink plenty of water and other fluids to keep yourself hydrated. It’s vital to fight dehydration that can occur due to reduced food intake. So, drink unsweetened, homemade lemonade, smoothies, and vegetable juices. Coconut water, buttermilk, and infused water are other fluids you can consume in between meals to ensure you get nutrients even if you don’t have sufficient food intake..
  1. Avoid foods with a strong smell: If you can’t stand the smell of your favorite food now, you aren’t alone. Food aversion due to a particular smell is fairly common in early and also later stages of pregnancy in some cases. If the smell of a particular food is bothering you, try masking its smell with other aromatic foods or herbs.
  1. Consume prenatal vitamins: Take your prenatal vitamins daily. If you have any insufficiency or deficiency, pay special attention to consuming supplements. Talk to your doctor to know if you need any additional vitamins or minerals. You may also consider consulting a nutritionist to make a well-balanced meal plan suited for your appetite.

Besides, seek prompt medical guidance if you are completely unable to eat. Your healthcare professional may prescribe medicines that can reduce nausea or vomiting and help regain your appetite.

Note: Chronic appetite loss can cause undernutrition, leading to a higher risk of poor fetal growth, low birth weight, and preterm labor.

Reasons For Appetite Loss During Second Trimester

Most women overcome nausea and vomiting by the 14th week of pregnancy (6). However, it may continue for a few more months or until the end of pregnancy for some women. Then, several women experience reduced appetite due to their growing bellies, which press on their stomachs, making them feel full quickly. Rising progesterone levels is another issue that may reduce appetite by making the gastrointestinal movement sluggish and slowing down digestion. Mental health conditions, such as anxiety and prenatal depression, may also affect appetite.

According to research, depression may reduce one’s appetite, especially for healthy food, and increase intake of unhealthy foods (7). Poor diet quality can affect the mother and her unborn baby’s health. Hence, if you feel anxious or depressed, contact your healthcare provider. Don’t shy away from opening up about mental health blues. Instead, get them treated so that they don’t affect your eating habits negatively.

On the other hand, Vitamin C is vital for facilitating several physiological functions, including your baby’s tooth and bone development.
