Non-communicable diseases (NCDs) are medical conditions that are not caused by infectious agents and cannot be transmitted from person to person. Three common examples of NCDs are hypertension, diabetes, and peptic/gastric ulceration.

1. Hypertension:
- Meaning: Hypertension, also known as high blood pressure, is a chronic medical condition characterized by elevated blood pressure in the arteries.
- Causes: The exact cause of hypertension is often unknown, but risk factors include genetics, unhealthy lifestyle choices (such as poor diet, lack of physical activity, and smoking), obesity, stress, and certain underlying medical conditions.
- Mode of transmission: Hypertension is not communicable and cannot be transmitted from person to person.
- Major clinical signs and symptoms: Hypertension is often asymptomatic, but some individuals may experience symptoms like headaches, dizziness, blurred vision, chest pain, and shortness of breath in severe cases.
- Treatment: Treatment for hypertension typically involves lifestyle modifications (such as a healthy diet, regular exercise, weight management, and stress reduction) and medication to control blood pressure.
- Prevention and control: Preventive measures include maintaining a healthy lifestyle, regular blood pressure check-ups, and early intervention if diagnosed with hypertension.

2. Diabetes:
- Meaning: Diabetes is a chronic metabolic disorder characterized by high blood sugar levels due to the body's inability to produce or effectively use insulin.
- Causes: Type 1 diabetes is caused by an autoimmune reaction that destroys insulin-producing cells in the pancreas, while type 2 diabetes is primarily caused by lifestyle factors such as obesity, unhealthy diet, physical inactivity, and genetics.
- Mode of transmission: Diabetes is not communicable and cannot be transmitted from person to person.
- Major clinical signs and symptoms: Common symptoms include frequent urination, excessive thirst, unexplained weight loss, fatigue, blurred vision, slow wound healing, and recurrent infections.
- Treatment: Treatment involves blood sugar monitoring, lifestyle modifications (such as a healthy diet, regular exercise, weight management), oral medications, insulin therapy, and regular medical check-ups.
- Prevention and control: Prevention measures include maintaining a healthy weight, engaging in regular physical activity, consuming a balanced diet, and avoiding tobacco and excessive alcohol consumption.

3. Peptic/Gastric Ulceration:
- Meaning: Peptic or gastric ulceration refers to the formation of open sores in the lining of the stomach or upper small intestine.
- Causes: The primary cause of peptic ulcers is infection with the bacterium Helicobacter pylori (H. pylori). Other factors that can contribute to ulcer formation include long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs), excessive alcohol consumption, smoking, and stress.
- Mode of transmission: Peptic ulcers are not communicable and cannot be transmitted from person to person.
- Major clinical signs and symptoms: Symptoms may include abdominal pain, bloating, heartburn, nausea, vomiting, and weight loss.
- Treatment: Treatment involves a combination of antibiotics to eradicate H. pylori infection, medications to reduce stomach acid production, and lifestyle modifications (such as avoiding NSAIDs, alcohol, and smoking).
- Prevention and control: Prevention measures include practicing good hygiene, avoiding excessive use of NSAIDs, limiting alcohol consumption, quitting smoking, and managing stress levels.

It is important to note that these are general descriptions, and individual cases may vary. Consulting a healthcare professional is recommended for accurate diagnosis, treatment, and management of these conditions.
