Digging Deeper – The10 Signs To Stop Water Fasting

1. Stomach Pain

signs to stop water fasting

The natural acids present in your stomach sit idle and might create a situation of intermittent fasting stomach pain. The stomach acid might come out as acid reflux or develop other symptoms of fasting such as ulcers, damage to intestinal walls, stomach pain, a burning sensation in the stomach, or chest pain while fasting.

The water fasting stomach pain is common but should be taken seriously. 

To cut the acid to relieve stomach pain while fasting, you should try to have more alkaline substances that can raise your gut pH factor.

You can have warm water to see if that works. Half a spoon of baking soda or sodium bicarbonate might help since it is an alkaline substance ideal for settling stomach acids.

You can also try cold water with effervescent granules of ENO salt, a mixture of citric acid and sodium bicarbonate commonly available on the market to relieve acidity. Do consult a doctor for the best course of action.

2. Throat Pain

symptoms to stop fasting

Water fasting can affect the thyroid-stimulating hormones released from the pituitary gland in the brain and, in turn, affect the T3 (Triiodothyronine) and T4 (Thyroxine hormone) released by the thyroid gland.

These play a major role in metabolism, regulating body temperature and energy. Poor thyroid functioning makes it difficult to lose weight and makes the body tired.

The thyroid gland has to work harder to preserve muscle and fat while fasting and meet the body’s energy needs. The thyroid’s actual function is downregulated due to nutritional insufficiency, which can manifest as a pain in the throat.

A slight discomfort might wither away, but you might want to stop fasting if the pain continues for long. You should have foods rich in proteins and carbohydrates or have seafood once you start your regular diet after fasting.

3. Losing Consciousness

The feeling of light-headedness and loss of consciousness are some common symptoms seen during water fasting. It could be due to falling blood pressure, high blood sugar and low insulin levels, low electrolytes, nausea while fasting, and dehydration. Some vitamin and mineral deficiencies such as B12, iron, and magnesium can also lead to loss of consciousness. 

High blood sugar or hyperglycemia can be particularly harmful as it can cause diabetic ketoacidosis (DKA), where the body starts producing toxic substances in the absence of insulin. 

If you are not feeling well and have fainted, you can lie down with your feet high to improve blood circulation to your brain. You can go out in the open air and have water. Avoid heavy meals immediately after water fasting as it can worsen your nausea.

4. Vomiting and Nausea

You will see some people experiencing fasting nausea or throwing up while fasting, which could be acid reflux.

Too much acid in the stomach might make you feel nauseous, leading to ​​stomach pain during fasting, and you might end up vomiting. Your vomit may include bile, the digestive enzyme released by the liver as it collects unused in your stomach. 

If you are wondering, does throwing up break your fast? The answer is NO! since you aren’t ingesting anything. You may experience vomiting sometimes, but it does not break your fast.

However, if you’re throwing up, you should stop fasting. At this time breaking the fast or not should be the last thing on your mind. To ease nausea symptoms, break your fast and consume plain water, mint tea, ginger tea, or lemon soda. After breaking your fast, avoid eating substantial meals right away.

5. Breathing Issues

Some complain of shortness of breath while water fasting due to the shortage of salt in the body. If you drink too much water without adding the necessary minerals such as sodium, magnesium, and potassium, you might have restrictive breathing. 

You can try having pink salt mixed in water if you suffer from a breathing issue; if you still do not feel better within 15-20 minutes, you can consider breaking your fast. 

6. Insomnia

The melatonin hormone released by the pineal gland plays a role in regulating the sleep-wake cycle. Studies indicate that water fasting can reduce melatonin secretion as the pineal gland needs a little amount of glucose to function well. However, some animal studies suggest that obese individuals might not be more affected by insomnia-related issues as lean people. 

Another reason for chronic insomnia could be rising cortisol levels during prolonged fasting. In extreme cases, it might create mental health issues, so you should stop fasting immediately.

7. Extreme Fatigue, Headache, and Weakness

fatigue from fasting

You can have severe fatigue as the body is devoid of the needed fuel for its normal functioning. Some people experience extreme weakness and loss of energy as fasting symptoms while performing their day-to-day activities.

You can opt for less intensive exercises like yoga or walking and try exerting your body as little as possible. You can have a nap during the day to boost your energy levels. Some people also suffer from fasting headaches due to caffeine withdrawal. You should stop fasting if any of these symptoms go out of hand. 

8. Lack of Concentration

Water fasting can bring along all kinds of mood swings and irritability due to protruding hunger off and on, making it difficult to concentrate. The ghrelin hormone responsible for hunger also plays a role in memory performance. Tolerating hunger is particularly difficult when the body cannot shift into ketosis to use stored fats. 

You might have to break your water fast and choose to go for a fat-only diet without any carbohydrates that will still keep you in ketosis. By doing this, your body might continue autophagy without raising insulin. You can also consider having MCT oils (medium-chain triglyceride) to stay in ketosis.

9. Diarrhea or Constipation

Diarrhea could be due to excessive salt and water in the gastrointestinal tract. Typically, there are fewer chances of catching diarrhea during fasting. However, you can experience diarrhea after breaking fast since the bowel’s ability to function well reduces when not used for a long time. 

Other reasons for experiencing diarrhea during or after fasting could be the wrong diet before or after breaking the fast. You should eat carefully post long water fast to avoid inflammatory bowel diseases (IBDs) or refeeding syndrome, which could even be fatal. 

You might suffer constipation as the body loses too much fluid or undergo diuresis during the initial days of fasting. Lack of fiber in the diet could also lead to intolerable constipation that might force you to consider pausing your fast.

Though diarrhea is common during intermittent fasting, there are techniques to avoid it or minimize the severity of it. To know more in detail, read Diarrhea After Fasting: What Are The Causes And Cures

10. Feeling too Hot or Cold

Some people experience a fall in body temperature while water fasting as blood flow increases to use up stored fat. Another reason for cold sensitivity is a fall in blood sugar while water fasting. 

Doing light exercises might warm up your body. If you cannot resist the cold, you can have your preferred tea, coffee, or green tea. If you are feeling too hot, it can be an indicator of pre-menopausal hot flashes in women. Discuss with your doctor.
