Healthy pregnancy starts with mindful eating, not missed meals.
Why Fasting During Pregnancy should be Avoided
Fasting during pregnancy is a complex issue. While many women observe fasts for religious or personal reasons, but a pregnancy demands more nutrients and energy than usual. Fasting can cause serious problems like low blood sugar, dehydration, and fatigue — all of which may impact both mother and baby.
What Risks Does Fasting Pose?
1. Low Blood Sugar (Hypoglycemia)
When you don’t eat for long hours, your blood sugar can drop dangerously low. During pregnancy, this is more dangerous because your body and the baby both need constant glucose supply for growth.
2. Dehydration
Skipping fluids for long periods can lead to dehydration. This can strain the kidneys, reduce amniotic fluid, and cause dizziness or urinary issues.
3. Fatigue and Weakness
Your body already works extra hard when pregnant. Fasting increases stress on body, causing weakness, exhaustion, or fainting, the risks which can’t be afforded during pregnancy.
4. Potential Impact on the Baby
Because your body may divert resources to keep you stable, the baby’s development could suffer. There might be risks to growth, placental health, or other complications (especially if fasting for long stretches).
When Fasting Might Be Safer — With Care
Experts say not all fasts are equal — risks depend on:
- The stage of pregnancy
- How healthy the mother is
- Duration of fast
- Meal taken before and after the fast
If a woman is in overall good health, some doctors may allow modified fasting, but only under strict medical supervision.
Go for Modified version of Strict Fasting

- Talk to your doctor before considering any fast
- If insisted on fasting (for religious reasons), use a modified fast: eat nutritious meals before and after the fast, sip fluids, choose energy-rich foods
- Monitor your body and consider dizziness, weakness, or lack of fetal movements as warning signs
- Rest more, and avoid strenuous work
- Prefer light healthy meals over long fasting periods
What to Eat & Drink During a Modified Fast
- Complex carbohydrates (e.g., whole grains, oats)
- Good proteins (e.g., lentils, eggs, milk)
- Fruits and vegetables rich in vitamins and minerals
- Hydrating fluids (coconut water, soups, infused water)
- Avoid deep fried, sugary, or heavy foods

Conclusion
While fasting during pregnancy may be a meaningful practice for many, it comes with real risks. Fasting during pregnancy should never be taken lightly — always consult your doctor first. Your health and your baby’s safety are far more important than any ritual.
