FAQ
Is this site a substitute for seeing a doctor?
No. This site provides general health information for educational purposes. It cannot diagnose conditions or replace professional medical evaluation. Always consult a healthcare provider for personal medical advice.
When should I go to the emergency room?
Go to the ER for chest pain, difficulty breathing, severe bleeding, sudden severe headache, weakness or numbness on one side, suicidal thoughts, severe allergic reactions, or any condition that seems life threatening. When in doubt, call emergency services.
What is the difference between a viral and bacterial infection?
Viruses cause colds, flu, COVID 19, and most sore throats. They do not respond to antibiotics. Bacteria cause strep throat, urinary tract infections, and pneumonia. Only bacterial infections benefit from antibiotics.
How do I know if my fever is dangerous?
In adults, a very high temperature, fever lasting more than a few days, or fever with severe headache, stiff neck, a rash, difficulty breathing, or confusion needs medical attention, and severe symptoms warrant an emergency call. Babies under 3 months with a temperature of 38C 100.4F or higher need urgent medical advice.
Should I take antibiotics for a cold?
No. Colds are caused by viruses. Antibiotics only kill bacteria. Taking antibiotics for viral infections does not help and contributes to antibiotic resistance, making future bacterial infections harder to treat.
What screenings do I need?
Recommendations vary by country, age, sex, and risk factors. Common screening programmes cover blood pressure, cholesterol, bowel cancer, breast cancer, cervical cancer, and bone density, with ages and intervals set by national health authorities. Discuss what applies to you with your doctor.
