Approximately 200,000 people in Hong Kong have serious obesity problems, that is, BMI (Body Mass Index) is higher than 30. Some people choose to undergo weight loss surgery, such as stomach reduction, gastric band, and gastric hydroballoon. However, there is a certain degree of surgery. risk.
A surgeon revealed that a swallowable gastric hydroballoon introduced in Hong Kong last year does not require the use of an endoscope or anesthesia, but it can lose 10 to 15% of body weight just like a traditional gastric hydroballoon.

Huang Jianhong, a specialist in surgery at CUHK Hospital, said that after the "gastric ball" is placed on the stomach, it can reduce stomach capacity and the feeling of fasting.
The traditional gastric ball is made of silicone and needs to be implanted and removed through an endoscope. Therefore, the patient needs to undergo two intravenous anesthesia, which is "always invasive to the patient."
This type of gastric hydroballoon has a 2% chance of "leakage" within half a year. Because of its thicker body, if the water in the hydroballoon drains away, the outer membrane may "clog the intestines" and "have to be carried out by surgery."

Swallowed gastric globules are as big as the fingertips and pump up after swallowing
Hong Kong introduced a swallowable gastric hydroballoon last year. It is a capsule about the size of a finger. The capsule is connected to a throat and the patient can swallow it by himself like a medicine.
The doctor will also X-ray the patient to confirm the position of the capsule.
When the capsule reaches the stomach, the doctor will inject about 500ml of liquid through the throat to "pump" the gastric ball. The process takes about 10 minutes.
Huang Jianhong pointed out that after the injection is completed, the doctor will remove the hose and the valve of the connection position will automatically close.
After 4 months, the outer membrane material will melt by itself and the liquid will flow out. Because the outer membrane of the new gastric ball is made of polyurethane, each layer is only 0.1 mm thin, and can pass through the intestine and be excreted by the patient.
The liquid in the gastric hydrosphere is physiological saline and food-grade preservatives, which are harmless to the human body.
The doctor will also X-ray the patient again after 4 months to ensure that the gastric hydrosphere has been discharged from the body.

It has been used by more than 20 local patients so far
Huang Jianhong said that the gastric ball is suitable for first-degree obese people with a BMI of more than 27.5, and severely obese people can also use the gastric ball to lose weight before surgery, which is more beneficial for future surgery, because people with a BMI of more than 50 receive anesthesia. If you have the opportunity to "suffer", it is safer to have surgery after weight loss.
So far, more than 20 patients in Hong Kong have received the new gastric ball.
He emphasized that although the gastric hydroballoon can help patients lose weight, the most important thing is to establish good eating habits within 4 months of putting the gastric hydroballoon. Only after the gastric hydroballoon can be taken out can you truly control your weight.

Huang Jianhong pointed out that there will be slight discomfort when swallowing the capsules. About seven to eight adults can swallow them on their own. Some people need help with tools.
After putting in the gastric ball, you may feel nausea, stomach cramps and other sensations. The first two or three days are harder and you need to take anti-vomiting drugs.
He also reminded that gastric globules are not suitable for people with gastritis, gastric ulcers, gastric surgery, long-term use of thin blood pills, severe liver cirrhosis, etc.
The gastric ball set is priced at about 40,000 to 80,000 yuan, and different hospitals charge differently.
