Background: Prevalent illnesses including gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP) can complicate pregnancies and cause birth abnormalities. Objective: Evaluation of the birth outcomes in pregnant women who also have gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP). Methods: 1170 females who were pregnant were evaluated in the past for the data. In order to determine which pregnant women were hypertensive and went on to acquire gestational diabetes, we first identified them. There were three groups created: the control group, the gestational diabetes with HDN group, and the normal comparison group. Initial demographics were assessed, along with comorbidities and birth results. Results: 186 of them later developed gestational diabetes, and 352 of the women showed signs of pregnancy-related hypertension. These three groups' demographic traits were comparable. In comparison to the non-HDN+GDN group, the rate of caesarean deliveries was considerably greater in the HDN and GDN+HDN groups. Similar to this, the rates of all 11 negative infant outcomes all rose significantly more and were all greater in the HDP/GDM group than in the comparison group. Premature births were significantly more common in women with preeclampsia or eclampsia than in women with only HDP or the healthy control group. Conclusion: Risk of adverse outcomes for the unborn child in pregnant women with HDP, HDP/GDM, preeclampsia, or eclampsia is continuously rising.Early delivery is frequently suggested in order to lower maternal morbidity and mortality in such cases.
