Chronic kidney disease (CKD) is a condition in which abnormalities in kidney function or structure persist for 3 months or longer. In the early stages there are often no particular symptoms, so the disease may go unnoticed and be discovered only after it has progressed considerably. People who have diabetes or high blood pressure, or who have a family history of kidney disease, need regular testing. If a health checkup reveals a kidney abnormality, please consult a medical specialist to confirm it.

Early Detection and Management of Liver Disease

#liver disease, #liver cancer, #cirrhosis, #hepatitis B, #hepatitis C, #fatty liver, #nonalcoholic steatohepatitis, #hepatectomy, #minimally invasive surgery, #early screening, #alcohol abstinence, #lack of energy, #listlessness, #persistent tiredness, #nausea, #feeling about to vomit, #vomiting

The liver is a 'silent organ.' Even as damage progresses, there are no obvious symptoms in the early stage, so fatigue, loss of appetite, and weight loss are often dismissed as minor, and the disease is often discovered only after it has progressed to cirrhosis or liver cancer. Regular checkups are the most important way to protect liver health.

Tongue Cancer

Tongue cancer is a malignant tumor that develops in the tongue and accounts for about 10 to 15% of all head and neck cancers. Because early symptoms resemble those of stomatitis (mouth sores), it is often left untreated and found late. Treatment outcomes tend to be better when the cancer is detected early, so if you have a sore on the tongue that does not heal or a lump you can feel, please consult a medical specialist without delay.
