Worldwide most common problem during pregnancy is–

Correct option is D

Sol. Iron deficiency anemia is the most common nutritional disorder seen during pregnancy worldwide. It affects nearly 40% to 50% of pregnant women, especially in low- and middle-income countries. The growing fetus increases the mother’s iron demand, which if unmet through diet or supplements, leads to anemia. It causes fatigue, breathlessness, low birth weight, and can increase the risk of maternal death. WHO recommends iron-folic acid supplementation during pregnancy for prevention.
Explanation of each option:
· (a) Diabetes – Incorrect. While gestational diabetes is a significant concern, its global prevalence is lower than iron-deficiency anemia. It usually affects 5–10% of pregnancies.
· (b) Pre eclampsia – Incorrect. Although serious, pre-eclampsia affects about 3–5% of pregnancies. It’s not as globally prevalent as iron deficiency anemia.
· (c) UTI – Incorrect. UTIs are common during pregnancy but vary regionally. They are generally managed well and are less frequent than iron-deficiency anemia.
· (d) Iron deficiency Anaemia – Correct. This condition remains the leading global health problem in pregnancy, especially where nutrition is inadequate or prenatal care is poor.
