Hypertension, also known as high blood pressure, is a chronic medical condition in which the blood pressure in the arteries is persistently elevated. It is a major risk factor for cardiovascular disease, including heart attack and stroke.

Signs and Symptoms

Hypertension is often called the "silent killer" because it typically has no symptoms until it has caused significant damage to the heart and arteries. Some people with high blood pressure may experience headaches, dizziness, or shortness of breath.

Causes

The exact cause of hypertension is often unknown, but several factors can contribute to its development, including:

• Genetics
• Unhealthy diet, particularly high salt intake
• Lack of physical activity
• Obesity
• Excessive alcohol consumption
• Smoking

Diagnosis

Hypertension is diagnosed by measuring blood pressure using a sphygmomanometer. A reading of 140/90 mmHg or higher is generally considered high.

Treatment

Treatment for hypertension typically involves lifestyle changes and medication. Lifestyle changes may include:

• Eating a healthy diet
• Reducing salt intake
• Engaging in regular physical activity
• Maintaining a healthy weight
• Limiting alcohol consumption
• Quitting smoking

Medications used to treat hypertension include diuretics, beta-blockers, ACE inhibitors, and calcium channel blockers.

Complications

If left untreated, hypertension can lead to serious health problems, including:

• Heart disease
• Stroke
• Kidney failure
• Vision loss

Prevention

Preventing hypertension involves adopting a healthy lifestyle, such as eating a balanced diet, exercising regularly, and avoiding tobacco and excessive alcohol use.

Red eyes refer to a condition where the sclera (the white part of the eye) appears red or bloodshot. This condition can result from various causes, ranging from minor irritations to more serious health concerns. Red eyes are often a symptom of other eye conditions or diseases.

Causes

Red eyes can be caused by several factors, including but not limited to:

• Allergies: Allergic reactions can cause the eyes to become red, itchy, and watery.
• Conjunctivitis: Also known as pink eye, this infection or inflammation of the conjunctiva leads to red, irritated eyes.
• Dry Eye Syndrome: This occurs when the eyes do not produce enough tears or the tears evaporate too quickly, causing irritation and redness.
• Eye Strain: Extended periods of screen time or reading can cause eye strain, leading to redness.
• Contact Lens Wear: Overuse or improper use of contact lenses can irritate the eyes, making them red.
• Environmental Factors: Smoke, dust, wind, and chlorine in swimming pools can irritate the eyes and cause redness.
• Injuries: Any injury to the eye can cause redness due to inflammation and swelling.

Symptoms

Besides the obvious redness of the sclera, symptoms associated with red eyes may include:

• Itching
• Pain
• Swelling
• Discharge
• Sensitivity to light
• Blurred vision

Treatment

Treatment for red eyes depends on the underlying cause. Some common treatments include:

• Artificial Tears: For dry eyes or irritation caused by environmental factors.
• Antihistamines: For allergies.
• Antibiotics: For bacterial infections like conjunctivitis.
• Warm Compresses: For relief from discomfort and to help with the removal of discharge.
• Rest and proper hygiene: Especially important for contact lens wearers and those experiencing eye strain.

Prevention

Preventive measures for red eyes include:

• Avoiding known allergens.
• Taking regular breaks during tasks that strain the eyes.
• Wearing sunglasses to protect against UV rays and environmental irritants.
• Maintaining good eye hygiene, especially for contact lens wearers.
• Using humidifiers in dry environments to help keep the eyes moist.
