Most women tend to gain more weight during pregnancy because of eating surplus food. Binge eating on the pretext that they should eat for two during pregnancy can lead to serious concerns later on. Research indicates that expectant mothers may be setting themselves up for increased health risks by overeating while pregnant. Consuming excess food while pregnant can negatively impact a baby’s health as well. The recommended measure of additional calories during the second trimester is 340 calories per day while in the third trimester, it is 450 calories a day with likely weight gain of about 18 kg or less.

Is It Normal to Overeat in Pregnancy?

It is normal for some women to experience increased appetite and consume more calories during pregnancy. However, overeating excessively is not recommended. It’s essential to focus on nutrient-dense foods and maintain a balanced diet to support both the mother’s and baby’s health. Consulting with a healthcare provider for personalized advice is advisable.

Why Should You Avoid Excessive Eating in Pregnancy?

Eating too much during pregnancy can adversely affect the well-being of a pregnant woman. Some of the reasons for avoiding excessive eating in pregnancy are:

1. Excess Weight Gain

Lack of controlled eating during pregnancy can result in undue weight gain. Gaining excessive weight during pregnancy may adversely affect a pregnant woman physically like increased leg pain, back pain and unwarranted pressure on the joints. It can also intensify the risk of developing varicose veins and haemorrhoids.

2. Gestational Diabetes

Overeating when pregnant and disproportionate weight gain can expose a pregnant woman to a greater risk of developing gestational diabetes. A pregnant woman’s increased sugar levels can raise the baby’s insulin levels and blood sugar levels which his body may store as fat thus putting him at risk of obesity and type 2 diabetes.

3. Emergency Caesarean Sections

Consuming too many calories during pregnancy can affect the unborn baby’s weight. The possibility of giving birth to a large baby increases which can heighten the chances of a caesarean section and plausible complications.

4. Heartburn

Heartburn is a common complaint during pregnancy. As pregnancy advances, the growing uterus can crowd the digestive tract putting more pressure on the stomach and intestines. Eating excessively during this time may worsen the instances of indigestion and heartburn.

5. Problems for the Unborn Baby

A baby will possibly be born too big in case the mother gains excess weight owing to overeating. At the time of delivery, a larger baby may injure his shoulders or the mother’s birth canal. Large babies are also prone to experience respiratory distress, low blood sugar, the danger of obesity and heart disease after birth.

6. Pre-eclampsia

Overindulgence during pregnancy may cause pre-eclampsia or high blood pressure in pregnant women which can jeopardise the mother and baby’s health. Pre-eclampsia can become a reason for preterm delivery. Usually, in such cases, complete bed rest or even medicines will be advised.

7. Post-baby Weight Loss

A pregnant woman may easily be able to shed her expected weight gain after delivery. But in case she gains more than usual weight, it can require extra effort. If you overeat, you will have a tough time losing your pregnancy weight.

8. Bad Habits

By constantly binge-eating, you may be establishing a new bad habit. You may not be able to turn off the overeating switch even after delivery which can result in additional health issues.

How to Control Over-Eating When Pregnant?

Most pregnant women may wish to ask how to stop overeating during pregnancy. Some of the possible ways to do so can be:

1. Light Exercises

Engaging in light exercises, such as walking, can help control overeating during pregnancy. Physical activity not only supports overall health but also helps regulate appetite.

2. Adequate Hydration

Maintain proper hydration levels as dehydration can sometimes be mistaken for hunger. Drinking enough water can help curb unnecessary cravings and control overeating.

3. Stick to a Healthy Diet

Prioritize a balanced and nutritious diet throughout pregnancy. Avoiding junk food is crucial, as it provides little nutritional value and may contribute to excessive calorie intake.

4. Identify Emotional Triggers

Recognize emotional triggers that lead to overeating. Emotional eating is common during pregnancy, and finding alternative ways to manage stress, such as meditation or listening to soothing music, can help prevent excessive food consumption.

5. Practice Mindful Eating

Be mindful of your eating habits. Pay attention to hunger and fullness cues, savor each bite, and avoid distractions during meals. Mindful eating promotes a better connection with your body’s natural signals.

6. Small, Frequent Meals

Opt for smaller, more frequent meals instead of large, infrequent ones. This approach can help maintain steady blood sugar levels and prevent extreme hunger, reducing the likelihood of overeating.

7. Plan Healthy Snacks

Keep nutritious snacks readily available to avoid reaching for unhealthy options. Planning and preparing healthy snacks in advance can help you make better food choices throughout the day.
