2. Effects of obesity during pregnancy
2.1. To pregnant women Being obese during pregnancy puts you at risk for a number of serious health problems:Gestational diabetes : Diabetes that begins to occur during pregnancy. This condition can put you at risk for a cesarean section. Women with gestational diabetes are also more likely to develop diabetes in the future, and the condition can be passed on to the baby. Obese women during pregnancy must be screened for gestational diabetes at an early stage. Preeclampsia: A disorder related to high blood pressure that occurs during or after pregnancy. This is a dangerous disease that affects the entire body of a woman. Preeclampsia causes kidney and liver failure and can lead to seizures (a condition called eclampsia). Some cases lead to stroke. Severe cases require urgent treatment to avoid these complications. The baby is more likely to be born early. Sleep Apnea: A condition in which breathing stops for a short time during sleep. This phenomenon is related to obesity. During pregnancy, sleep apnea not only causes fatigue, but also increases the risk of high blood pressure, pre-eclampsia, eclampsia, and heart and lung conditions.

Miscarriage: Obese women have a higher rate of miscarriage than women of normal weight. Birth defects: Babies born to obese mothers are at increased risk for birth defects, such as heart defects or neural tube defects. Difficulty performing diagnostic tests: Too much body fat can make it difficult to diagnose certain problems with your baby's anatomy during an ultrasound. Checking the baby's heart rate during labor is also more difficult when the mother is obese. Macrosomia: In this condition, the baby's body is larger than normal. As a result, there is an increased risk of the baby being harmed during labor. For example, a baby's shoulder may get stuck during birth. Macrosomia can also lead to a woman having a cesarean section. Babies that are too big are more likely to be obese later in life. Preterm birth: Problems associated with obesity during pregnancy, such as preeclampsia, can lead to premature birth. Premature babies often don't develop as fully as babies born after 39 weeks of pregnancy. Stillbirth: The higher the BMI, the higher the risk of stillbirth.
