Is daily consumption of coconut water good for hydration?

Answer:

Coconuts are easy to find, reasonably priced and have a moderately sweet taste so they are a favorite especially during the summer. However, nutritionists advise that we should only consume 2-3 coconuts every week, about 500 ml each time. If we exceed this amount, we run the risk of having some side effects such as:

Hypotension

Coconut water is regarded as a drink rich in potassium, which is a necessary nutrient for those suffering from high blood pressure. Nevertheless, an excessive amount of coconut water can result in potassium surplus, hypotension, dizziness, and even fainting.

Indigestion

When you drink a large amount of coconut water in a short period of time, you can get indigestion. Your stomach accumulates too much water, so your abdomen will stretch, causing discomfort.

Risk of hyperglycemia

According to nutrient analysis, every 100 ml of coconut water contains about 5g of glucose. Therefore, those having diabetes should keep an eye on their daily coconut water intake to avoid the risk of hyperglycemia and other serious complications.

Electrolyte imbalance

Electrolyte imbalance, also known as electrolyte disorder, occurs when the potassium and sodium levels in the blood fall below or go over safe limits. Frequent coconut water intake will cause fluctuations in these two blood indicators and slow down blood circulation to the heart, destabilizing the heart rate or, more dangerously, making your heart stop beating.

Increased pressure on the kidneys

You will notice that when you drink a large amount of coconut water, your urination frequency will increase. This phenomenon can cause the kidneys to "work too hard" to excrete waste, causing the kidney’s parenchymal cells to swell temporarily. If this phenomenon persists, your kidney function may decline.
