What Causes Vomiting During Fasting? Does It Break Your Fast?

Does vomiting break your fast? Have you ever wondered about this? Vomiting while fasting is usually caused by the digestive system issue.

On the other hand, it can also happen due to the food and drinks you consume during suhoor or iftar.

Although vomiting while fasting is not a serious issue, it often raises doubts about the validity of the fast.

So, does vomiting while fasting actually break the fast? Without further ado, let’s find the explanation below!

Does Vomiting Break the Fast?

Vomiting while fasting does not necessarily break the fast. However, it is important to note that only unintentional vomiting does not break the fasting.

If vomiting is done deliberately, such as by inserting a finger into the throat to induce vomiting, the fast is considered invalid.

If you vomit while fasting, immediately expel any remaining food from your mouth and rinse with water to clean out any residue.

Make sure not to swallow the vomit. However, if it is accidentally swallowed, the fast remains valid.

What Causes Vomiting During Fasting

To prevent vomiting while fasting, it is best to understand its causes first.

Here are some common causes of vomiting during fasting:

1. Digestive System Adaptation

For some people who do not fast regularly, their circadian rhythm (the body’s internal system that regulates various functions over 24 hours) may not yet adjust to the fasting schedule or restricted eating times between iftar and suhoor.

This new adaptation can trigger nausea and vomiting while fasting. However, this condition usually disappears once the body fully adapts after a few days of fasting.

2. Consuming Oily Foods at Suhoor

Oily foods contain high amounts of fat that cause the stomach to take longer to digest.

Additionally, consuming oily foods can make you feel thirsty more quickly. If not balanced with adequate water intake, dehydration can occur. 

As a result, nausea often arises during fasting in the afternoon.

3. Eating Too Quickly or Overeating

The stomach needs time to digest food properly. 

Eating too quickly or in excessive amounts can overwhelm the stomach, making it difficult to process the food.

When this happens, the digestive system may force the food back up which leads to vomiting.

4. Consuming Spicy Foods at Suhoor

Some people cannot eat without spicy flavors.

However, keep in mind that consuming too much spicy food at suhoor is not ideal, especially for those with stomach issues.

Spicy foods can induce a rapid increase in stomach acid, which may lead to nausea and vomiting.

5. Sleeping Immediately After Suhoor

Going to sleep right after suhoor can cause people with GERD to experience a rapid rise in stomach acid. As a result, leading to nausea and vomiting.

Sleeping immediately after eating puts pressure on the stomach, which contributes to this issue.

How to Prevent Vomiting While Fasting

Vomiting while fasting can be very uncomfortable.

To prevent this from happening, here are some steps you can take:

1. Limit Oily or Spicy Foods

As mentioned earlier, oily or spicy foods can interfere with stomach function during digestion which increases the risk of vomiting.

To avoid this, limit your intake of these foods, especially during suhoor.

Instead, consume nutritious foods high in fiber to ensure your body's hydration needs are met.

2. Eat Slowly and in Moderation

During suhoor, eat in reasonable portions to avoid nausea from overeating.

Eating slowly and in moderation helps the stomach digest food more efficiently.

3. Avoid Sleeping Immediately After Suhoor

Ideally, you should wait 2 to 3 hours before sleeping after eating.

This habit allows the digestive system to have enough time to process the food properly.

That is why, you need to give it a break of 2-3 hours before sleeping. If you must sleep after suhoor, try doing so in a sitting position to reduce the risk of acid reflux.

4. Drink Enough Water

To prevent dehydration due to lack of fluid intake, make sure to drink enough water during suhoor.

You can follow the 2-4-2 drinking rule, which means, two glasses of water at iftar, four glasses at night, and two glasses at suhoor.

In relation to that, you can prepare AQUA to meet your daily water needs at home.

AQUA is drinking water sourced from natural mountain springs, available in gallon, bottle, and cube packaging.

AQUA gallon is ready-to-drink water with a tightly sealed double-injection cap for extra security. You can stock up on the 19-liter AQUA gallon for your family at home.

Meanwhile, for iftar or suhoor on the go, you can opt for the conveniently packaged AQUA bottle. So, wherever you have suhoor or iftar, make sure #AQUADULU!

5. Consult a Doctor

If vomiting persists and causes weakness, it’s best to see a doctor for proper medical treatments.

Vomiting while fasting often occurs due to dehydration which leads to nausea and vomiting.

Therefore, it is important to always ensure your body stays hydrated by drinking enough AQUA, the healthiest drinking water, both during suhoor and iftar.

Don't forget to choose high-quality drinking water like AQUA! Created by nature, 100% PURE mineral water for the holy month.
