What causes swollen feet in children?

There are both physiological and disease reasons for children's swollen feet. The physiological reason is mainly that the child walks too much and is too active in daily life, which may cause this phenomenon. In addition, if the child likes to eat some heavy-tasting foods and consumes too much salt, this phenomenon may occur. Be alert to swelling of the feet caused by some diseases.

What causes swollen feet in children?

Physiological causes

1. Standing or walking for a long time

Due to the effect of gravity and continuous tension in the lower limb muscles, blood return slows down, venous blood return is obstructed and edema occurs.

2. Excessive salt intake

After eating a lot of salt, drinking a lot of water will also cause changes in certain hormone levels in the body, leading to tissue edema.

Causes of the disease

1. Heart

The weakened heart pumping ability can easily lead to blood stasis in peripheral blood vessels, making edema more likely to occur.

2. Liver

The liver is where plasma proteins are synthesized. If the liver function is damaged, it is easy to cause a decrease in protein in the plasma, which will cause body fluids to be retained in the tissue spaces and produce edema.

3. Kidneys

The kidney's drainage ability is weakened, and the water and salt components in the body cannot be excreted in time, which makes edema prone to occur.

4. Nutrition

Poor physical condition is often said to be caused by insufficient nutrition in the body, which means that people do not pay attention to their own nutrient absorption in daily life. In fact, edema is one of the symptoms of malnutrition. If some people suddenly appear swollen and edematous, but do not eat well, it may be edema caused by malnutrition. When nutrition is insufficient, the protein content in the body decreases, the plasma protein content is low, and edema is prone to occur.

5. Endocrine

The disorder of secretion of certain hormones that regulate water and electrolytes in the body can easily cause abnormal water and salt metabolism and lead to edema.

6. Blood vessels and lymphatic vessels

Varicose veins, venous thrombosis, lymphatic reflux obstruction and other factors may also cause blood and tissue fluid stagnation and edema.

7. Thyroid

In addition to the above reasons, certain medications, leg and foot injuries, obesity, menstruation, etc. can all cause swollen legs and feet. For middle-aged and elderly people, the most common causes of swollen legs and feet are excessive salt intake, senile edema, heart, liver and kidney diseases, and vascular and lymphatic dysfunction.
