Gestational diabetes is the condition of diabetes that detected for the first time during pregnancy. Similar to other types of diabetes, gestational diabetes also has an impact on how the cells use sugar (glucose), but in pregnant women. Women are usually screened for gestational diabetes between 24 and 28 weeks of pregnancy, but a woman may be tested earlier if at higher risk. Gestational diabetes can affect the pregnancy as well as the baby's health. Any complication during pregnancy is worrisome, but there is good news. Expectant mothers can control this condition by eating healthy foods, exercising regularly, and if required taking medication as prescribed by the doctor. 

In women with gestational diabetes, blood glucose levels are usually restored to normal after delivery. But if a woman has had gestational diabetes, her chances of getting type 2 diabetes are higher. In such cases, the doctor will advise getting blood sugar checked more often. Maintaining blood glucose levels can keep the mother and her baby healthy and prevent any complications during delivery. Onlymyhealth editorial team talked to Dr. Ashu Rastogi, MD, DM, MNAMS, FACE, FRCP (Edin.), Associate Professor, Department of Endocrinology and Metabolism, Vice President, Diabetic Foot Society of India, about the risk factors and prevention measures for gestational diabetes.

What causes Gestational Diabetes?

Gestational diabetes occurs when the body is unable to make enough insulin during pregnancy. Insulin is a hormone secreted by the pancreas, and it acts like a key to let blood sugar into the body for use as energy. A woman's body produces more hormones during pregnancy and goes through many other changes, such as weight gain. These changes can lead to body's cells to use insulin less effectively, which is a condition called insulin resistance. Insulin resistance increases the body's need for insulin.

All pregnant women have some insulin resistance during late pregnancy. However, some women may be resistant to insulin even before they get pregnant. They may start pregnancy with an increased need for insulin and may be more likely to develop gestational diabetes. Various risk factors in women that can lead to gestational diabetes are as follows:

● Hormonal changes (during pregnancy, hormone levels change, making it difficult for the woman's body to process blood sugar effectively and this can result in increased blood sugar levels)

● Being overweight or obese

● Having a family member with diabetes 

● Having a history of gestational diabetes or prediabetes

● Having polycystic ovary syndrome (PCOS) or any other health condition that can lead to fluctuations in insulin

● Having high blood pressure, high cholesterol, heart disease, or other medical complications

● Not being physically active

● Having given birth to a large baby previously (weighing more than 9 pounds, i.e., 4.1 kg)

What can be done to prevent gestational diabetes?

Following are some simple steps that can help in reducing the risk of developing both gestational diabetes and type 2 diabetes, both before and during pregnancy:

● Aiming to eat healthy food: Consume more fruits, vegetables and whole grains in daily diet. Eat food rich in fibre and low in fat and calories.

● Being physically active: Regular exercise before and during pregnancy can prevent the risk of developing gestational diabetes. Perform at least 30 minutes of moderate activity daily along with a brisk walk.
