1. RESPIRATORY AND CIRCULATORY COMMON DISEASES

2. Circulatory Common Diseases

3. Coronary Artery Disease Occurs when a substance called plaque builds up in the arteries that supply blood to the heart (called coronary arteries). Plaque is made up of cholesterol deposits, which can accumulate in your arteries. When this happens, your arteries can narrow over time. This process is called atherosclerosis.

4. HEART ATTACK A heart attack, also called a myocardial infraction, occurs when a section of the heart muscle dies or gets damaged because of reduced blood supply. Coronary Artery Disease (CAD) is the main cause of heart attack. A less common cause is a severe spasm of a coronary artery, which also can prevent blood supply from reaching the heart.

5. High Blood Pressure High blood pressure or hypertension means the force or pressure of the blood flowing through the vessels is consistently too high. High blood pressure can lead to stroke, loss of vision, heart failure, heart attack, kidney disease, and reduced sexual function.

6. Aortic Aneurysms Aortic aneurysms affect the main artery in the body. It means the artery wall has weakened, allowing it to widen or “balloon out.” An enlarged artery could burst and become a medical emergency.

8. ASTHMA Asthma is a serious condition in which the small airways of the affected person's lungs suddenly constrict when they are exposed to certain triggers, such as dust mites, pollen, exercise, or even dry air .

9. Chronic obstructive pulmonary disease (COPD)

10. EMPHYSEMA which happens due to damage to the tiny air sacs in the lungs, affecting your ability to move air in and out of your body

11. CHRONIC BRONCHITIS which leads to persistent inflammation or irritation of the airways and the formation of thick mucus

12. INTERSTITIAL LUNG DISEASE (ILD) ILD refers to a group of conditions that can cause scarring, called fibrosis, in the lungs. When scar tissue forms in the lungs, it can stiffen lung tissue and make it harder to breathe.
