What is swelling

Edema is the accumulation of excess fluid in the subcutaneous tissue beneath the skin . Also called edema. If your feet are swollen in the evening and your shoes feel tight, or your face feels puffy when you wake up in the morning, it is often due to swelling. As a way to check if there is swelling, press the swollen area with your finger for 10 to 20 seconds, and then release your finger quickly. I can say Swelling can also make you feel sluggish, heavy, and tired, especially in your legs.

Cause of swelling

There are several possible causes of swelling. First, as a mechanism that causes swelling, swelling is caused by a decrease in blood flow in the body. Oxygen and nutrients needed by the body are delivered to the body by blood. At that time, carbon dioxide and waste products made from cells are received and returned to the heart. This is because when the muscles of the body move, the blood flow is encouraged and blood is returned to the heart, but when the muscles do not move, the blood flow becomes stagnant and swelling occurs.

  • For transient swelling
    1. Swelling due to immobility of muscles : If you work at a desk or stand for a long time without moving your muscles, the calf pumping action that returns blood to the heart weakens and blood flow weakens, resulting in swelling. To do.
    2. Swelling from too much salt: Swelling from too much salt is caused by the body's ability to maintain a constant salt concentration, which causes the body to retain water in an attempt to dilute the salt concentration.
    3. Swelling due to changes in female hormones : During menopause, estrogen decreases and the balance of female hormones is disturbed, and the autonomic nerves that control vasoconstriction and dilation tend to be disturbed. It is believed that the disturbance of the autonomic nervous system leads to poor blood circulation and swelling.
  • For chronic swelling
    • Swelling can also occur if there is a problem with organs such as the heart, kidneys, or liver. It is characterized by the fact that it often does not heal even after a few days. In this case, it is recommended that you consult a medical institution as there is a possibility that you have a hidden illness.

How to improve swelling

There are several measures to prevent and improve swelling that can be started immediately, so if you feel swelling enough to worry about, try the following methods. Exercise, diet, and other things you can easily incorporate into your daily life, so let's start to the extent that you don't feel stressed.


Swelling caused by stagnation of bodily fluids such as blood and lymph. Stretching is a quick and easy way to clear this stagnation. It can be improved just by stretching the whole leg, such as the neck and shoulders, where you usually don't notice it. Even just bending your knees and turning your ankles will change the flow of blood considerably. If you have the time and place, light jogging or yoga is also good.


Bathing is recommended because the blood flow improves when the body warms up . It's best to soak in a lukewarm bath, but if you don't have a bathtub or don't have time, just a footbath is also effective.

It is also effective to massage the swollen area to improve the flow of blood and lymph . Start by massaging the extremities of the body, such as the feet and hands, farthest from the heart. By massaging from the extremities toward the lymph nodes, the flow of lymph is promoted more. If the entire foot is swollen, massage from the tip of the foot toward the base of the foot.

drink enough water

You might think that to prevent bloating, you should drink less water so that your body doesn't retain excess water. However, when the human body feels that there is not enough water, it works to retain water somehow, so water accumulates in the body. Even if you have a lot of water in your body, not drinking water can actually cause swelling, so be sure to drink enough water.

Eat foods that are good for bloating

Potassium is an effective nutrient for swelling. Potassium has the function of excreting sodium (salt) from the body as urine . Typical foods that contain potassium include bananas, apples, spinach, Japanese mustard spinach, and avocados. Other vegetables and fruits contain a lot of it, so be sure to take it actively. However, if you have kidney problems, consult your doctor, as too much potassium can cause pulse problems.

Also, protein is said to improve swelling. A protein called albumin in the blood plays an important role in preventing swelling. Albumin is involved in the regulation of the amount of water in and outside the blood vessels, and when the amount of albumin in the blood is insufficient, water flows out of the blood vessels, causing swelling. Keeping the right amount of protein in your blood can help prevent swelling1).

Avoid foods that cause swelling

The body always works to keep the salt concentration in the body constant. So when your diet is high in salt, your body retains water in an attempt to reduce its salt concentration. As a result, water accumulates and swelling occurs2 ). Processed foods are often made with a high salt content, so try to choose a menu that does not consume too much salt.

Also, many people may feel that the swelling is terrible the day after drinking alcohol. Alcohol is a diuretic, so it dehydrates your body. In addition, the blood vessels in the body dilate, which temporarily improves blood circulation, but the body becomes dehydrated and drinking a lot of water causes swelling.


For those who are concerned about swelling even though they take care of the diet, exercise, and massage mentioned above, there is also a method to improve it with Chinese medicine. Kampo is not something that can be effective in an instant, so it's a good idea to make it a daily habit like a meal.

In addition, in Chinese medicine, there is an idea to eat a lot of root vegetables, fermented foods, ginger, etc., which warm the body and improve blood circulation, and to avoid sweet foods such as white sugar, which cool the body . In this way, you can also incorporate the knowledge of oriental medicine into your regular diet . It is also recommended because it will also give you knowledge to get closer to a healthy body.
