Will drinking water make you fat? Three groups of people with heart disease, liver and kidney dysfunction should be restricted

Drinking more water has many benefits, but many people worry about "Will drinking water make you fat?" Doctors point out that water itself has no calories, and drinking water in moderation will not increase weight, let alone get fat. However, three major groups, such as those with heart disease, liver and kidney dysfunction, will experience edema due to the inability to excrete water, leading to weight gain, so it is recommended not to drink too much water.

Dr. Zhou Shuoqu from the Department of Family Medicine at the National Shuanghe Hospital pointed out that water cannot cure diseases but it is a good way to maintain health. Drinking more than 2000cc of water a day can promote metabolism in the body, and drinking 500ml of water before meals can increase satiety, reduce calorie intake, and achieve weight loss effects. Even combined with vegetable and fruit fiber intake, it can effectively reduce the risk of weight regain.

Drinking too little water makes it difficult to feel full and more likely to gain weight

According to a study conducted by a research team from the University of Michigan, people who are dehydrated have a higher body mass index (BMI) than those who are well hydrated. The main reason for this is that when people feel dry mouth and tongue, they often mistakenly think that they are hungry and eat to satisfy it, which makes people who drink too little water more prone to obesity.

However, it is not enough to drink more water, you also need to drink just the right amount. The simplest way to calculate is to multiply each kilogram of body weight by 30. For the average person, the average daily intake of boiled water is about 1,800 to 2,000 cc. However, if you drink more than several liters (about 10 liters), you are likely to have symptoms of low blood sodium, dizziness, and "water intoxication."

Drinking more water has many benefits, but many people worry that drinking water will make them fat.

Drink more warm water and don’t drink water only when you are thirsty

Dr. Zhou Shuoqu emphasized that drinking less water in summer can easily cause heatstroke. In the clinic, it is often found that many people forget to drink water due to busy work. Therefore, he reminds people "don't wait until you are thirsty to drink water", because feeling thirsty means that the body has been dehydrated for a while. Drinking too little water may cause blood thickening in the body, which could sound a warning for your health.

Another thing to note is that the temperature of the water should be kept at room temperature or slightly warm, because water that is too hot may cause esophageal burns, and water that is too cold may irritate the stomach and cause discomfort. Usually in the summer, if office workers stay in an air-conditioned room for too long, it is recommended to drink slightly warm water, but boiled water at around 20°C is still better.

Drink more water if you're fine? 3 groups should be restricted

In addition, although "drinking more water is fine", the following three groups should limit their water intake:

1. People with heart disease should not drink too much water: because after a large amount of water enters the human body and is absorbed, the amount of body fluid will increase significantly, making the blood thinner and the blood volume increased, which increases the workload on the heart. The heart has to increase the strength and speed of blood delivery, which can easily cause health risks.

2. People with kidney disease should not drink too much water: Since these patients have renal insufficiency and reduced glomerular filtration rate, they are unable to excrete water and electrolytes normally. If they drink water without restraint at this time, it will increase the burden on the kidneys and cause edema.

3. It is not advisable to drink too much water in liver failure: because liver disease can cause albumin (maintaining plasma colloidal osmotic pressure) synthesis disorders. When the plasma colloidal osmotic pressure decreases, it will cause excessive accumulation of water in the tissues, often manifested as pleural effusion, ascites and lower limb edema. At this time, drinking water should be limited.
