Weather effect

Hot temperatures are associated with an increased risk of GDM, as it can lead to dehydration, stress, increased cortisol levels, and insulin resistance. Extreme cold temperatures can pose a health risk to pregnant women, especially those with underlying medical conditions such as GDM. Cold weather can cause constriction of blood vessels and raise blood pressure, which can be especially dangerous for women with high blood pressure or pre-eclampsia.


This is a serious health condition that can occur in pregnant women with GDM. The condition is associated with high blood pressure and can damage the liver and kidneys. Pre-eclampsia can be life-threatening for both mother and baby, causing premature labor or even stillbirth.

Premature delivery

Premature babies born before 37 weeks of pregnancy may have organs that are not fully developed and require special care in a neonatal intensive care unit (NICU). In addition, babies born prematurely may be at an increased risk of health problems later in life.



Macrosomia is a condition in which a baby is much larger than average. When a pregnant woman's blood sugar level is uncontrolled because excess sugar can cause the baby to grow too fast. This can increase the risk of complications during delivery, such as shoulder dystocia and the need for a caesarean section.

Other possible complications of GDM include:

respiratory distress syndrome.

Hypoglycemia in the child after birth.

Higher chance of developing type 2 diabetes later in life.


It is extremely important for pregnant women with GDM to take precautions during extreme weather conditions, hot or cold. Women should be advised to stay hydrated and avoid prolonged exposure to extreme temperatures. They should be urged to maintain a nutritious diet and exercise regularly even in inclement weather. Pregnant women with GDM may require more frequent monitoring of blood glucose levels during extreme weather conditions to ensure that their glucose levels remain stable and within a healthy range.

The effect of weather on GDM is an emerging area of ​​research. Weather conditions may significantly affect women's risk of developing GDM, although additional research is needed to fully understand the relationship. Identifying and addressing these risk factors can ensure the best possible outcome for both mother and baby.
