Causes of Decreased Appetite in the Third Trimester
To ensure the healthy development of the baby in utero, women must consume adequate nutrition during pregnancy. Appetite often changes throughout pregnancy: it typically decreases during the first trimester but increases during the second and third trimesters. However, some pregnant women experience a decline in appetite during the late stages of pregnancy. So, what causes decreased appetite in the third trimester? Below, we address this question.

Causes of Decreased Appetite in the Third Trimester
During the third trimester, some women notice a reduction in appetite—a phenomenon considered normal. This is primarily due to uterine enlargement compressing the stomach. Nevertheless, adequate nutrition remains essential during this period. Women may adopt a “small, frequent meals” approach—consuming six to eight smaller meals daily—and ensure sufficient intake of protein and energy. Easily digestible, semi-solid foods (e.g., soups, porridge, yogurt, or cheese) are recommended. Special dietary supplementation is generally unnecessary in late pregnancy, as fetal development is largely complete; maintaining a balanced, regular diet suffices. For constipation, increasing dietary fiber intake—such as fruits, vegetables, and whole grains—is advisable.

Knowledge Extension: Managing Decreased Appetite in the Third Trimester
1. Eat Small, Frequent Meals
Consume 6–8 small meals per day rather than large, infrequent ones. Avoid relying solely on liquid foods, as they may be poorly digested; instead, opt for semi-solid options such as cheese or yogurt.
2. Increase Fiber Intake
Consume ample fruits and vegetables. Limit intake of gas-producing, gastrointestinal-irritating foods—including starchy items, refined grains, and legumes—as these may exacerbate discomfort. Additionally, excessive stool accumulation in the colon can worsen bloating; therefore, adequate hydration is essential to support regular bowel movements.

The above outlines the primary reasons for decreased appetite during the third trimester. We hope this information is helpful to you.
