"The 6 Most Common Diseases and Health Conditions in the Elderly: What You Need to Know to Protect Your Loved Ones"

6 Common Diseases in Older Adults

Older adults are at greater risk of chronic and degenerative diseases because of age-related changes in the body, health behaviors, and medical conditions accumulated since younger adulthood. Six of the most common diseases among older adults—identified by sources including Ramathibodi Hospital, Bangpakok 3 Hospital, and other health information sources—are major problems that affect the quality of life of older people in Thailand:

• Stroke
  A condition in which blood flow to the brain is reduced because a blood vessel narrows, becomes blocked, or ruptures. This damages brain tissue and may cause weakness, paralysis, or sudden death. Warning signs include slurred speech, facial drooping, and weakness of an arm or leg.
• Ischemic Heart Disease
  Caused by narrowing or blockage of the coronary arteries, which reduces blood supply to the heart. It may lead to a heart attack, chest pain, or heart failure. Common symptoms include chest tightness and easy fatigue.
• Osteoarthritis of the Knee
  Caused by degeneration of the cartilage covering the knee joint. It is common in older adults and can cause knee pain, stiffness, and difficulty walking. Severe cases may make walking impossible.
• Hypertension
  Very common among older adults and often has no obvious symptoms. If left untreated, it increases the risk of heart disease, stroke, and chronic kidney failure.
• Alzheimer’s Disease / Dementia
  A condition caused by degeneration of brain cells, leading to worsening memory, forgetfulness, confusion, and personality changes. Close supervision and care may be needed.
• Diabetes Mellitus
  Caused by abnormalities in insulin production or function, resulting in high blood sugar. It is common in older adults and increases the risk of complications such as heart disease, kidney failure, and blindness.

Regular monitoring, annual health checkups, healthy exercise, appropriate nutrition, and good control of existing medical conditions can help reduce the risk and delay the onset of these diseases.
