5. Chronic Kidney Disease (CKD)
Chronic Kidney Disease (CKD) is a long-term condition in which the kidneys gradually lose their ability to filter waste products, excess fluids, and toxins from the blood. Because kidney damage usually develops slowly over months or years, many people do not notice symptoms until the disease has reached an advanced stage.
The kidneys play a vital role in maintaining overall health by regulating blood pressure, balancing electrolytes, producing hormones that support red blood cell production, and helping maintain healthy bones. When kidney function declines, waste products build up in the body, increasing the risk of serious health complications.
According to global health estimates, millions of people are living with CKD, and its prevalence continues to rise due to increasing rates of diabetes, hypertension, and obesity.
Stages of Chronic Kidney Disease
Healthcare professionals generally classify CKD into five stages based on the estimated glomerular filtration rate (eGFR):
- Stage 1: Mild kidney damage with normal kidney function
- Stage 2: Mild reduction in kidney function
- Stage 3: Moderate decline in kidney function
- Stage 4: Severe reduction in kidney function
- Stage 5: Kidney failure (end-stage kidney disease), often requiring dialysis or kidney transplantation
Early detection allows for better management and may slow disease progression.
Common Symptoms
In its early stages, CKD often causes no noticeable symptoms. As kidney function worsens, symptoms may include:
- Persistent fatigue
- Swelling in the feet, ankles, or hands

7. Hypertension (High Blood Pressure)
Hypertension, commonly known as high blood pressure, is one of the most widespread chronic diseases worldwide. It occurs when the force of blood against the walls of the arteries remains consistently higher than normal. Over time, this increased pressure can damage blood vessels and vital organs, including the heart, brain, kidneys, and eyes.
Hypertension is often called the “silent killer” because many people experience no symptoms until serious complications develop. Regular blood pressure screening is essential, especially for adults over the age of 40 or those with risk factors such as obesity, diabetes, or a family history of cardiovascular disease.
When left untreated, hypertension significantly increases the risk of heart attack, stroke, kidney disease, and heart failure.
What Is Considered High Blood Pressure?
Blood pressure is measured using two numbers:
- Systolic pressure: The pressure when the heart beats.
- Diastolic pressure: The pressure when the heart rests between beats.
Healthcare providers diagnose hypertension based on multiple blood pressure readings rather than a single measurement. Regular monitoring helps determine whether treatment or lifestyle changes are necessary.
Common Symptoms
Most people with hypertension experience no noticeable symptoms. However, severely elevated blood pressure may cause:
- Persistent headaches
