Short-term weight loss effects have been reported, but large-scale studies of long-term effects are still lacking. It calls for caution, or is not advisable, in certain groups such as people with diabetes mellitus, so please be sure to consult a medical specialist before starting.

Iron deficiency anemia is a condition in which a lack of iron in the body leads to a shortage of red blood cells.

If anemia persists for a long time, it can place strain on the heart, so identifying the cause and receiving appropriate treatment is important. If you suspect these symptoms, please consult a hematology-oncology specialist.

Kidney Cancer

Kidney cancer is a malignant tumor that develops in the kidney. There are almost no symptoms in the early stages, so it is difficult to notice on your own, and in most cases it is found incidentally during a health checkup. Even without symptoms, it is important to detect it early through regular health checkups. If an abnormal finding is detected or you have any concerns, please be sure to consult a medical specialist.

Kidney Transplant Process

#kidney transplantation, #kidney transplant, #living-donor kidney transplantation, #deceased-donor kidney transplantation, #immunosuppressants, #rejection, #end-stage kidney failure, #KONOS, #organ transplantation, #double vision, #overlapping images

Kidney transplantation is a surgery that transplants a healthy kidney into the body to replace a kidney that has lost its function. Unlike dialysis, it can restore most of the kidney's various functions (removing waste products, regulating electrolytes, secreting hormones that stimulate blood cell production, and others), which makes it one of the main treatment options for end-stage kidney failure. Whether and how to have a transplant depends on each patient's health condition, so please be sure to decide through consultation with a medical specialist.

Kidney Transplantation

Kidney transplantation is a surgery that transplants a healthy kidney into a patient with end-stage kidney failure, whose kidneys can no longer function properly. If the transplanted kidney functions normally, the patient may be freed from dialysis (a treatment that filters waste products from the blood using a machine), which can greatly improve quality of life. Ongoing care after surgery is very important, and please be sure to consult a medical specialist about anything related to transplantation.

Leukemia is a malignant tumor that arises from immature blood cells in the bone marrow. It is classified as acute or chronic, and as myeloid or lymphoid depending on the type of cell involved. Unlike in the past, advances in medicine, including targeted therapy, have expanded the treatment options. Please discuss the diagnosis and treatment plan thoroughly with a hematology-oncology specialist.

Liver Cancer

Liver cancer is a malignant tumor that develops in the liver, which is responsible for detoxification and nutrition in the body. The liver is called the 'silent organ' because there is no particular pain even when the disease becomes advanced. By the time symptoms appear, the disease has often already progressed considerably, so please do not judge on your own; be sure to have regular checkups and consult a medical specialist.

#liver cancer, #hepatocellular carcinoma, #cirrhosis, #hepatitis B, #hepatitis C, #hepatectomy, #liver transplantation, #Milan criteria, #ascites, #jaundice, #transarterial chemoembolization (TACE)

Liver cancer (hepatocellular carcinoma) is a malignant tumor that develops from the cells that make up the liver. Because there are almost no symptoms in the early stage, it is often found incidentally during health checkups. Regular checkups are especially important for people with chronic liver disease caused by hepatitis B, hepatitis C, or alcohol-related liver disease. The treatment method and prognosis differ depending on each patient's condition, so please consult a medical specialist before making any decisions.

Liver cirrhosis refers to a condition in which the liver has been damaged for a long time by various causes and has become hard. It is also called 'gangyeongbyeon' in Korean. When the liver hardens, it cannot perform its functions well. For an accurate diagnosis and treatment, please consult a medical specialist.

Liver transplantation is an operation that replaces a liver that has lost its function with a healthy liver, and it is one of the treatment options for several serious liver diseases, such as liver failure caused by cirrhosis and liver cancer. Since it was first performed in Korea in 1988, advances in technology and medication have led to more than 1,500 transplants a year at present, and the overall surgical success rate is reported to be about 90 to 95%. Liver transplantation is an important decision for both the recipient and the donor, so please discuss it thoroughly with your treating physician before making a decision.
