This document is meant purely as a source of information only; it should not be interpreted as providing any medical diagnosis, treatment or advice. Every pregnant woman experiences her pregnancy differently than another; therefore please consult your obstetrician/gynecologist/healthcare professional prior to changing your diet/lifestyle during the course of your pregnancy.

Pregnant Women-Pregnancy can be an exciting time in a woman’s life. There are numerous hormonal/metabolic changes that occur at this time, and for some women, there will also be an increase in blood sugar levels, known as gestational diabetes (GDM).

Generally speaking, GDM develops during the later stages of pregnancy, typically between weeks 24 through 40. Most women find that after they have given birth to their baby, the symptoms related to GDM will no longer affect them. It may be necessary to offer special care for both mother and child during their respective pregnancies to maintain the health of both the newborn child and the mother throughout the entire course of their pregnancy.

Fortunately for most pregnant women with GDM, compliance with an appropriate diet, doing regular exercises, and closely monitoring their blood glucose levels do allow them to manage (and in most cases control) GDM during gestation.

This guide contains:

1. An overview of GDM

2. A breakdown of how and why GDM occurs during pregnancy; 

3. Identify foods that will help regulate blood glucose levels; 

4. Limit the types of foods that Increase blood sugar levels in GDM.

5. Identify lifestyle habits that contribute to maintaining optimal health throughout pregnancy.

In summary, the primary objective of this guide is to assist mothers in remaining healthy and to support their growing babies.

Gestational Diabetes:

1.Gestational diabetes mellitus is a form of diabetes that develops during pregnancy. It occurs when the body does not produce enough insulin to handle the increased amount of blood sugar due to pregnancy.

2.Insulin is a hormone that helps to move glucose from the bloodstream into cells to provide energy.

3.During pregnancy, the hormones produced by the placenta can cause insulin to not work effectively. This is known as insulin resistance.

When the body is unable to compensate with more insulin production, blood sugar levels will rise.

Key Facts:

• Worldwide, gestational diabetes affects approximately 7% to 14% of pregnancies.

• Gestational diabetes typically occurs between weeks 24-28 of pregnancy.

• Most women can control it through diet and life-style changes.

• Some women may also require insulin therapy.

Identifying gestational diabetes early and managing it properly reduces complications.

How Gestational Diabetes effects mother and foetus in pregnancy and baby after birth:

If blood glucose levels remain elevated during pregnancy, both the mother and her child can be affected.

Effects on Mother:

• Increased risks of developing high blood pressure.

• Increased chances for C-section delivery.

• Greater risk for developing Type II Diabetes in later years.

Effects on Baby:

• Overweight baby at birth.

• Complications during delivery.

• Baby will likely have low blood sugar after delivery.

• Baby will be at significant risk for developing obesity later during childhood.

By getting proper care from your healthcare provider, these risks can be eliminated.

Common Risk Factors For Developing Gestational Diabetes:

A woman is more likely to develop gestational diabetes if any of these factors are present.

Some common risk factors include family history of diabetes, being overweight or obese at the start of pregnancy, having had gestational diabetes with a previous pregnancy, being over age 30, having polycystic ovary syndrome (PCOS), or having had a baby weighing more than 4,000 grams (about 9 pounds).

Women who have any of these risk factors may be screened early during the pregnancy:

Commonly, women who have gestational diabetes do not develop symptoms. Therefore, it is important to undergo routine screening tests for gestational diabetes.

There may be some mild symptoms that occur from time to time, such as:

• Increased thirst

• Increased frequency of urination

• Tiredness

• Blurred vision

All of these symptoms can also occur during normal pregnancies, so it is vital that blood glucose levels are checked to get the correct diagnosis.

How to Diagnose Gestational Diabetes.

Gestational diabetes is typically diagnosed by a doctor using a glucose tolerance test, which is usually performed during pregnancy between 24 and 28 weeks.

The following are components of this test:

 (1) Drinking a glucose solution

 (2) A blood sample will be taken 1 hour after you drink the glucose solution.

 (3) Sometimes, a second test known as a three-hour glucose tolerance test will be performed. If your blood sugar levels exceed the normal range, you are diagnosed with gestational diabetes.

Diet That Gestational Diabetic Females Can Take:

Eating properly can help you maintain and control your blood sugar levels and provide your unborn baby with adequate nutrition.

 The following are some guidelines for healthy eating while pregnant and having gestational diabetes:

• Eat smaller meals throughout the day.
