Diabetes mellitus leads to high blood glucose due to disturbance in insulin secretion or sensitivity. Diabetes mellitus type 1 results from insufficient insulin release. Diabetes mellitus type 2 and gestational diabetes occur mainly due to insulin resistance which is associated with obesity and pregnancy. Diabetes is a chronic disease that needs three approaches for successive treatment which are food regimen (diet), exercise, and medication (either by insulin or pills). These three treatment strategies should occur together. Insulin treatment is typically used to treat type 1 diabetes, and on the occasion, that type 2 patients don't react to different drugs. Medications that don't contain insulin are given either as oral pills or by infusion. The most distinguished of these medications and the first to be utilized to treat diabetes is metformin. Doing a pancreas transplant is especially valuable for type 1 patients. There is no negative impact of diabetes on the marital relationship because high blood glucose level doesn't affect the menstrual cycle and ovulation happens normally. There is no issue with the wedding a woman with diabetes as diabetes doesn't influence the productivity of the patient, as this woman can manage her sugar level appropriately. Some diabetic women have little sexual desire but unlike diabetic men, they have no difficulties during or after sex. Controlling the blood glucose level during pregnancy is very important for the security of both the mother and the baby. Women with gestational diabetes could begin breastfeeding as non-diabetic women, however, the time of breastfeeding in women with gestational diabetes was two months not as much as that of uninfected women.
