Pregnancy is a time of significant changes, and weight management is a common concern for many expectant mothers. In this expert Q&A session, Dr. Smily answers key questions about weight gain and loss during pregnancy to help mothers make informed decisions.

Dr. Smily: It is generally not advisable to lose weight during pregnancy, as the mother’s nutrition is crucial for fetal development. If you experience weight loss or intend to manage your weight, consult your obstetrician to determine the best approach for your pregnancy.

Weight gain during pregnancy occurs due to the development and enlargement of the fetus, placenta, and amniotic sac over the course of the trimesters.

Weight gain is typically expected in the second and third trimesters. Poor weight gain may result from several factors, including severe nausea and vomiting, known as hyperemesis gravidarum. This condition can cause significant weight loss and dehydration, which may be harmful to both the mother and the baby.

A healthy pregnancy weight is determined by pre-pregnancy Body Mass Index (BMI). BMI is calculated by dividing weight in kilograms by height squared (m^2). Each BMI category has a recommended range of weight gain during pregnancy.

Meal plans vary based on pre-pregnancy BMI and medical conditions. In general:

A balanced diet should include carbohydrates, proteins, fibers, and essential supplements such as folic acid and calcium.

Weight gain during pregnancy is normal, and the amount varies based on pre-pregnancy BMI. However, significant weight loss is not recommended, and medical consultation is advised in such cases.

Mothers who are underweight at 20 weeks should seek medical advice to ensure a healthy pregnancy. A well-balanced diet rich in proteins, healthy fats, and essential vitamins can help with weight gain.

For a pre-pregnancy BMI of less than 18, a weight gain of up to 18kg may be considered normal. Monitoring caloric intake and ensuring a balanced diet with fruits, vegetables, moderate protein, and carbohydrates can help manage weight gain.

Gestational diabetes requires close monitoring of glucose levels. A dietitian can help design a meal plan with controlled carbohydrate intake and calorie counting to manage weight and blood sugar levels effectively.

Weight gain varies based on BMI. For those with a BMI between 18-24.9 kg/m², a total weight gain of 12-16kg is considered normal.

Eating frequent small meals can help manage nausea. A balanced diet with carbohydrates, proteins, fiber, and adequate water intake is recommended.

Experiencing extreme vomiting, diarrhea, and an inability to keep food down can lead to severe weight loss and dehydration. If you face these symptoms, seek medical attention immediately.

For a pre-pregnancy BMI of 29, a weight gain of 7-11kg is generally considered healthy. Reducing sugary foods and focusing on nutrient-dense meals with protein, fruits, and vegetables can help maintain a balanced pregnancy weight.

Maintaining a healthy weight during pregnancy is essential for both mother and baby. While weight gain is a natural part of pregnancy, drastic fluctuations—whether loss or excessive gain—should be discussed with a healthcare provider. A well-balanced diet, proper meal planning, and medical guidance ensure a healthy pregnancy journey.
