Lifestyle diseases are long-term health conditions caused by the way we live. They are also known as non-communicable diseases (NCDs). Unlike infections, these illnesses develop slowly over time and are linked to habits related to diet, exercise, sleep, and stress.

In India, the most common lifestyle diseases include diabetes, high blood pressure, heart disease, obesity, thyroid disorders, PCOS, high cholesterol, and certain mental health conditions. These diseases have become common even among younger people due to sedentary routines, processed food diets, and increased workplace stress.

Most Common Lifestyle Diseases in India

Diabetes (Type 2 Diabetes):
India is known as the diabetes capital of the world. Type 2 diabetes occurs when the body cannot use insulin properly. Symptoms include frequent urination, increased thirst, tiredness, slow wound healing, and sudden weight changes.

Hypertension (High Blood Pressure):
Hypertension rarely has symptoms but can damage the heart, kidneys, and brain over time. Stress, salt-heavy diets, and lack of physical activity are major triggers.

Heart Disease:
Blocked arteries, weakened heart muscles, and irregular heart rhythms contribute to heart disease. Chest pain, breathlessness, fatigue, and swelling are common warning signs.

Obesity:
A growing concern in urban and rural India. Obesity increases the risk of diabetes, heart disease, sleep disorders, and joint pain.

Thyroid Disorders:
Hypothyroidism and hyperthyroidism affect metabolism. Symptoms range from weight gain, fatigue, and hair fall to anxiety and heart palpitations.

PCOS (Polycystic Ovary Syndrome):
A hormonal condition affecting young women. It causes irregular periods, weight gain, acne, excess facial hair, and fertility issues.

High Cholesterol:
Too much LDL cholesterol can block arteries, increasing the risk of stroke and heart attack.

Fatty Liver Disease:
Common among those who eat high-fat diets or consume alcohol. Symptoms include digestion issues, tiredness, and abdominal discomfort.

Stress-Related Disorders:
Chronic stress contributes to insomnia, anxiety, depression, and high blood pressure.
