Drinking water on an empty stomach can have several disadvantages.
Here are a few to consider:
It can lead to acid reflux: When you drink water on an empty stomach, it can increase the level of acid in your stomach, which can cause acid reflux and heartburn.
It can cause stomach cramps: Drinking water on an empty stomach can cause stomach cramps and discomfort, especially if you drink large amounts at once.
It can interfere with digestion: Drinking water before a meal can dilute stomach acid, which can make it harder for your body to break down food and absorb nutrients.
It can lead to hyponatremia: Drinking too much water on an empty stomach can lead to a condition called hyponatremia, in which the level of sodium in your blood becomes too low. This can cause symptoms such as headache, nausea, and confusion.
It can affect the metabolism: Drinking water on empty stomach in the morning can slow down the metabolism, which can make it harder for your body to burn calories and lose weight.
It is recommended to drink water before or after meals, rather than on an empty stomach. And also it’s good to drink water in small sips throughout the day.
