Gestational Diabetes Diet: Food To Eat And What to Avoid

Gestational diabetes is a common condition that affects many pregnant women. While it can be managed with proper care and lifestyle changes, a well-planned diet plays a crucial role in controlling blood sugar levels and ensuring a healthy pregnancy.

In this blog post, we will explore the essential foods to include and avoid in your diet to effectively manage gestational diabetes.

What is Gestational Diabetes?

Gestational diabetes is a type of diabetes that develops during pregnancy. It occurs when the body cannot produce enough insulin to meet the increased demands of pregnancy, resulting in high blood sugar levels. Gestational diabetes typically develops around the 24th to 28th week of pregnancy and affects about 2-10% of pregnant women.

During pregnancy, hormonal changes can interfere with insulin function, leading to insulin resistance. Insulin resistance causes blood sugar levels to rise, which can pose risks to both the mother and the baby if left unmanaged.

Risk factors that increase the likelihood of developing gestational diabetes include:

Obesity
Family History of Diabetes
Previous Birth of a Large Baby:
Age
Prediabetes
Low Physical Activity
