Health conditions & symptoms

Clinical topic guides covering causes, symptoms, and when to seek care.

Weakness

Feeling weak or unusually tired can have many causes — from poor sleep and dehydration to anemia, thyroid problems, or infections. Understanding common patterns helps you decide when self-care is reasonable and when a doctor's evaluation is important.

Fatigue

Fatigue is persistent tiredness or low energy that does not improve adequately with rest. It can overlap with weakness and often signals that your body needs medical evaluation when it lasts or affects your quality of life.

Joint Pain

Joint pain can affect one joint or many, and may result from injury, overuse, arthritis, or infection. Understanding where and how your joints hurt helps determine whether you need rest, physiotherapy, or specialist evaluation.

Knee Pain

Knee pain affects people of all ages — from sports injuries in younger adults to osteoarthritis in older adults. Location, timing, and triggering activities help doctors identify the cause.

Back Pain

Back pain is one of the most common reasons people seek medical care. Most episodes improve with time and conservative care, but certain warning signs require prompt evaluation.

Headache

Headaches range from mild tension-type discomfort to disabling migraines. Most are not dangerous, but sudden severe headaches or new patterns after age 50 warrant prompt medical attention.

Migraine

Migraine is a neurological condition causing recurring headaches often accompanied by nausea, light sensitivity, and visual disturbances. Proper diagnosis helps reduce attack frequency and severity.

Fever

Fever is a temporary rise in body temperature, usually in response to infection. It is a symptom rather than a disease — understanding accompanying features helps decide when home care is enough and when a doctor should evaluate you.

Stomach Pain

Abdominal or stomach pain has many possible causes — from indigestion and gastritis to appendicitis and gallstones. Location, severity, and associated symptoms guide urgency.

Depression

Depression is more than occasional sadness — it is a medical condition that affects mood, energy, sleep, and daily functioning. Recognizing symptoms early helps people access appropriate professional support.

Anxiety

Anxiety is a normal response to stress, but when worry becomes persistent, overwhelming, or interferes with daily life, professional support can help you regain balance and function.

Hypertension

Hypertension often causes no symptoms until complications develop — which is why regular blood pressure checks matter. When diagnosed, it is usually manageable with lifestyle changes and medicines prescribed by a doctor.
