Karwa Chauth 2026: How should women who take daily medication for blood pressure or blood sugar observe the Karwa Chauth fast?

Karwa Chauth is one of the most significant festivals for married women. On this day, women observe a *nirjala* (waterless) fast, praying for the long life of their husbands.

Health experts advise that women observing the Karwa Chauth fast should remain vigilant about their health. Many women who observe this fast may also be on daily medication—whether for thyroid issues, diabetes, high blood pressure, or other chronic conditions—where consistent, uninterrupted dosage is essential.

This raises the question: can those who require daily medication observe the Karwa Chauth fast? Let’s find out what the experts have to say.

Fasting for those with pre-existing health conditions

Health experts emphasize that individuals with pre-existing conditions—such as diabetes, high blood pressure, or other chronic illnesses—must be extra cautious regarding their health. In such cases, one should not fast without consulting a doctor.

Whether or not a woman who takes daily medication can fast depends on the nature of her medical condition and the specific type of medication she is prescribed.
Some medications must be taken on an empty stomach, while others require food. Consequently, skipping a dose or altering the timing of your medication on your own can be harmful.
Therefore, it is crucial to consult a doctor before fasting and to understand the correct timing for taking your medications.

What should those on daily medication do before fasting?

General physician Dr. Shekhar Ranjan explains that if you take daily medication, you should consult your doctor before fasting to determine whether it is safe to adjust the timing of your doses. Every medication has its own specific requirements; for instance, some thyroid medications are best taken on an empty stomach, whereas others must be taken with food. Taking certain medications on an empty stomach—or without any food or drink—can lead to serious health complications.

Never skip a dose or alter your medication regimen on your own without consulting your doctor. Individuals who frequently experience high blood sugar or high blood pressure should avoid staying on an empty stomach for long periods or skipping doses of their medication.

Which patients need to exercise extra caution?

For patients with diabetes, remaining without food for an extended period can cause blood sugar levels to drop or spike. Furthermore, those taking insulin or certain other medications face an increased risk of their blood sugar dropping too low. Such individuals must pay close attention to both their medication regimen and their dietary intake.

Meanwhile, patients with high blood pressure must ensure they take their medication regularly and monitor their blood pressure consistently.

If you experience dizziness, tremors, cold sweats, fainting, or extreme weakness while fasting, seek medical assistance immediately.
