The common infections in old people are as a result of a weak immune system. However, they can always boost their lymphocytes by embracing a healthy lifestyle such as workouts
These are the diseases that afflict old people;
Lung diseases
Ageing makes the air sacs to become shapeless which in turn become baggy. Furthermore, the muscles and other lung tissues lose their ability to perform their activity effectively and this is why you find that most of them have tuberculosis, dry cough, asthma and other lung related-complications.
2. Cardiovascular diseases
Heart attack, stroke and heart failure are among the chronic diseases.
Ageing impairs the heart muscles and subjects the heart to pump the blood harder. This is due to the fact the aorta and blood capillary walls are so thicker and less flexible.
3. Kidney and bladder problems
Old men are fond of suffering from these outlined conditions. More so the kidney stones, nephritis and urinary tract infections.
4. Adult-onset diabetes
Diabetes occurs when the pancreas fails to produce enough insulin hormone required to regulate the amount of glucose. The disease is common in old people.
