What Is Gestational Diabetes Causes Symptoms Diagnosis and Treatment
Gestational diabetes is a type of diabetes which was raised up for the first time during pregnancy (gestation). As other types of diabetes are concerned, gestational diabetes affects the procedure our cells use sugar (glucose). Gestational diabetes causes high blood sugar that can highly affect the pregnancy and baby's health. While any complication regarding pregnancy is concerning, there is no good news. Expectant mothers can easily control gestational diabetes by eating healthy foods, exercising and, if required, taking medication. Keeping the blood sugar in control can keep the mother and the baby healthy and stops a difficult delivery to take place.
Women affected with gestational diabetes, blood sugar generally returns to normal soon after delivery. But if the mother had gestational diabetes, she has a higher risk of getting type 2 diabetes. The mother needs to get tested for changes in blood sugar more frequently.For many women, gestational diabetes doesn't produce any noticeable signs or symptoms. Increase in thirst and more-frequent urination are possible symptoms.
Gestational Diabetes Causes
The researchers haven’t yet found out the root cause of gestational diabetes . Some of the researchers say that the main gestational diabetes cause is the increase of weight of the women before the pregnancy . No other such gestational diabetes cause has been found out yet.
Generally, many hormones work up to keep the blood sugar levels at an optimum level.During pregnancy, hormone levels may increase and decrease , which makes it much harder for the mother’s body to breakdown blood sugar efficiently. This makes your blood sugar increase.
Gestational Diabetes Diagnosis
The doctor will give the mother a glucose examination or glucose screening test. The woman will be required to drink something sweet to raise your blood sugar. An hour later, the woman undergoes a blood test to see how her body has processed all that sugar. If the result of the test shows that her blood sugar is higher than a particular level, usually around 200 milligrams per deciliter (mg/dL), she will need an oral glucose tolerance test which means checking your blood sugar after going without food and having a 3-hour glucose test.
If she was at high risk but the undergone test results are normal, the doctor might test her again later in the timeline of pregnancy to make sure she still doesn't have it.
Gestational Diabetes Treatment
If the mother has gestational diabetes, the doctor needs to carry out the treatment as soon as possible to keep the mother and her baby healthy during her pregnancy and delivery. Your doctor will ask the mother to:
To check her blood sugar levels four or more times a day
To check her urine for ketones, chemicals that mean that her diabetes isn’t under control
To maintain a healthy diet.
To exercise and maintain it as a habit.
The doctor will continuously keep track of her weight and her baby’s development. Doctors might give her insulin or another medicine to keep her blood sugar under control. The gestational diabetes treatment is essential for the mother during pregnancy.
Risk Factors For Gestational Diabetes
Some women tend to have a greater risk to obtain gestational diabetes. Risk factors for gestational diabetes consist of the following:
Overweight and obesity are a major problem regarding women.
A lack of physical exercise.
Previous history of gestational diabetes or prediabetes.
Polycystic ovary syndrome can be a major risk factor for Gestational diabetes.
If the mother has a history of delivering a baby weighing more than 9 pounds (4.1 kilograms).
Nonwhite race — Women who are black, American Indian, Asian American and Pacific Islander and those of Hispanic descent have a much higher risk factor for gestational diabetes development.
Solved Example
Is Gestational Diabetes Caused by Diet?
A: Eating sugary foods generally , do not increase the risk for gestational diabetes. If any mother is diagnosed with gestational diabetes it will be important to manage her carbohydrate intake to best manage her blood sugar levels. This would include managing her intake of sugary foods.
Did You Know?
When researchers and doctors from Columbia University’s College of Physicians and Surgeons studied the health data for 125 million US pregnancies for a study held in 2017 in the journal called BJOG: An International Journal of Obstetrics and Gynecology, the team made a surprising discovery: Rates of getting affected by gestational diabetes in pregnant mothers were 23 times higher in 2010 than in 1979.
FAQs on Gestational Diabetes in Pregnancy Explained Clearly
1. What is gestational diabetes?
Gestational diabetes is a type of diabetes mellitus that develops during pregnancy due to high blood glucose levels. It occurs when the body cannot produce enough insulin to meet the increased demands caused by pregnancy hormones.
- Usually diagnosed in the second or third trimester.
- Caused by increased insulin resistance from placental hormones.
- Often resolves after childbirth but increases future risk of type 2 diabetes.
2. What causes gestational diabetes during pregnancy?
Gestational diabetes is caused by pregnancy hormones that create insulin resistance, making it harder for cells to use glucose effectively. The placenta produces hormones such as human placental lactogen that interfere with insulin action.
- The pancreas normally increases insulin production during pregnancy.
- If insulin production is insufficient, blood glucose rises.
- Risk factors include obesity, family history of diabetes, and advanced maternal age.
3. How does gestational diabetes affect the baby?
Gestational diabetes can cause excessive fetal growth and metabolic complications in the baby due to high maternal blood glucose levels. Glucose crosses the placenta, stimulating the baby’s pancreas to produce excess insulin.
- May lead to macrosomia (large birth weight).
- Increased risk of newborn hypoglycemia after birth.
- Higher long-term risk of obesity and type 2 diabetes in the child.
4. What are the symptoms of gestational diabetes?
Gestational diabetes often has no noticeable symptoms and is usually detected through screening tests. When symptoms occur, they resemble other forms of diabetes.
- Increased thirst (polydipsia).
- Frequent urination (polyuria).
- Fatigue and blurred vision.
5. How is gestational diabetes diagnosed?
Gestational diabetes is diagnosed using a glucose tolerance test (GTT) that measures blood sugar levels after consuming a glucose solution. Screening usually occurs between 24 and 28 weeks of pregnancy.
- Initial oral glucose challenge test may be performed.
- If abnormal, a longer oral glucose tolerance test (OGTT) confirms diagnosis.
- Diagnosis is based on elevated fasting or post-glucose blood sugar levels.
6. How is gestational diabetes treated?
Gestational diabetes is treated by controlling blood glucose levels through diet, exercise, and sometimes insulin therapy. The goal is to maintain normal maternal blood sugar to protect both mother and baby.
- Medical nutrition therapy with controlled carbohydrate intake.
- Regular physical activity to improve insulin sensitivity.
- Insulin injections or oral medications if lifestyle changes are insufficient.
7. What is the difference between gestational diabetes and type 2 diabetes?
Gestational diabetes develops temporarily during pregnancy, while type 2 diabetes is a chronic condition characterized by long-term insulin resistance. Both involve high blood glucose, but their timing and persistence differ.
- Gestational diabetes usually resolves after delivery.
- Type 2 diabetes persists throughout life.
- Both share risk factors such as obesity and family history.
8. Can gestational diabetes go away after pregnancy?
Gestational diabetes usually resolves after childbirth because pregnancy hormones that cause insulin resistance decrease. However, affected women remain at higher risk of future diabetes.
- Blood glucose levels often return to normal within weeks postpartum.
- Follow-up glucose testing is recommended after delivery.
- There is an increased lifetime risk of developing type 2 diabetes.
9. Who is at risk of developing gestational diabetes?
Women with certain metabolic or genetic factors are at higher risk of developing gestational diabetes during pregnancy. Risk factors increase the likelihood of insulin resistance.
- Overweight or obesity.
- Family history of diabetes mellitus.
- Previous gestational diabetes or large baby.
- Polycystic ovary syndrome (PCOS).
- Advanced maternal age.
10. Why is insulin resistance important in gestational diabetes?
Insulin resistance is central to gestational diabetes because it prevents cells from effectively absorbing glucose from the blood. During pregnancy, placental hormones naturally increase insulin resistance to supply more glucose to the fetus.
- If the pancreas cannot compensate by producing more insulin, blood glucose rises.
- This leads to maternal hyperglycemia.
- Controlling insulin resistance helps maintain normal pregnancy metabolism.
