Pregnancy & Ramadan: A Trimester-by-Trimester Fasting Guide
SAFE TRIMESTER TO FAST DURING PREGNANCY: 1ST VS 2ND VS 3RD TRIMESTER

Ramadan is a meaningful and spiritual time for Muslims around the world. For pregnant mothers, however, fasting can come with questions and concerns especially about safety for both mother and baby.
One of the most common questions is: Which trimester is safest for fasting?
The answer depends on your body, your pregnancy condition, and your baby’s development. Here’s a complete guide to help you understand each trimester.
1ST TRIMESTER (WEEK 1–12): THE MOST CHALLENGING PHASE
The first trimester is when your body is going through major hormonal changes. Your baby’s organs are also beginning to form during this critical stage.
Common symptoms:
- Morning sickness
- Nausea and vomiting
- Extreme fatigue
- Loss of appetite
- Dizziness

Is fasting safe?
This trimester is often considered the most difficult for fasting, especially if you experience frequent vomiting or cannot keep food down.
Fasting may increase the risk of:
- Dehydration
- Weaknesses
- Low blood sugar
- Lack of essential nutrients
These nutrients are important for your baby’s early development.
When fasting may be unsafe:
- Severe morning sickness
- Weight loss
- Frequent dizziness
- Doctor advises against fasting
Summary:
Not the ideal trimester for fasting, especially if symptoms are severe.
2ND TRIMESTER (WEEK 13–26): THE SAFEST TRIMESTER TO FAST
The second trimester is often called the “golden phase” of pregnancy.
Your body has usually adjusted to pregnancy hormones, and most early symptoms improve.
Why it’s safer:
- Morning sickness usually reduces
- Energy levels improve
- Appetite returns
- Baby’s development is more stable
Many pregnant moms feel stronger and more comfortable during this stage.
Benefits of fasting during this trimester (if healthy):
- Lower risk of dehydration compared to first trimester
- Body adapts better to fasting
- Easier to maintain proper nutrition during non-fasting hours
Important reminder:
Even in this trimester, fasting is only safe if:
- Your pregnancy is healthy
- You have no medical complications
- Your doctor approves
Summary:
This is generally the safest trimester for fasting.

3RD TRIMESTER (WEEK 27–40): REQUIRES EXTRA CAUTION
The third trimester is when your baby grows rapidly and gains weight.
Your body also becomes heavier and needs more energy.
Common symptoms:
- Fatigue
- Back pain
- Heartburn
- Shortness of breath
- Increased hunger and thirst
Risks of fasting during this trimester:
- Dehydration
- Reduced energy
- Contractions (in some cases)
- Less energy for baby’s rapid growth
Your baby depends heavily on nutrients during this stage.
Fasting may be unsafe if:
- Baby is small
- You feel weak easily
- You have low blood pressure
- You have pregnancy complications
SIGNS YOU SHOULD STOP FASTING IMMEDIATELY
Regardless of trimester, stop fasting and consult your doctor if you experience:
- Severe dizziness
- Fainting
- Dehydration
- Reduced baby movement
- Strong weakness
- Contractions
Your health and your baby’s safety always come first.
Important Reminder in Islam
Pregnant mothers are given permission not to fast if fasting may harm them or their baby.
You can:
- Replace fasting later (qada), or
- Pay fidyah (based on religious guidance)
Your intention and your baby’s safety are what matter most.

TIPS IF YOU PLAN TO FAST
If your doctor says it’s safe, follow these tips:
During Sahur:
- Eat protein (egg, chicken, yogurt)
- Eat complex carbs (oats, whole meal bread)
- Drink plenty of water
- Avoid salty food
During Iftar:
- Breakfast slowly
- Drink water first
- Eat balanced meals
Rest:
- Avoid overexertion
- Take naps if needed
FINAL THOUGHTS
Every pregnancy is different.
While the second trimester is generally the safest time to fast, some mothers may not be able to fast at all — and that is completely okay.
