Watermelon is not a diuretic fruit. The reason why some people urinate frequently after eating watermelon is because the water content and sugar content in watermelon are high. Watermelon is the fruit with the highest water content. Basically, eating a watermelon is almost the same as drinking a liter of water. This is just pure water. Watermelon is rich in sugar, which can cause water to drain out of cells in some people's bodies, creating the illusion of "diuresis".

But not all people will be affected by the sugar in watermelon and experience frequent urination, only some people. Because the human body's conditions are different, the reactions are also different. The so-called "water in the cells is separated out", to give a simple example, just like a piece of white radish, if you put it in salt water, the white radish will slowly "shrink". This is because the water in the radish has been precipitated, that is, the water in the radish has been drained out.

Because this phenomenon only affects some people, and different physiques will have different reactions, it cannot be said that watermelon is a diuretic fruit.

However, those who want to pee frequently after eating watermelon can use this phenomenon to "treat" their illness. For example, people with urinary tract infections can eat more fruits to urinate frequently, thereby expelling toxins from the urinary system.

When the weather is hot in summer, people want to eat an iced watermelon to quench their thirst. There is no problem in eating a little. What needs to be reminded is that first of all, eating too much watermelon itself will have an impact on the human stomach and can affect the digestion capacity of the stomach. This is the reason why many people don’t want to eat after eating watermelon. Secondly, iced watermelon has a great impact on the stomach and even affects other organs in the body. Therefore, if the weather is hot in summer and you want to eat watermelon to relieve the heat, you need to pay attention to the amount of consumption, and do not rely entirely on your body's feelings to eat watermelon without restraint.

Generally speaking, watermelon is not a diuretic fruit. Frequent urination after eating watermelon is because some people have poor ability to absorb sugar, which causes the water in the cells to be precipitated.
