Patient questions
Frequently asked questions
Is Pulmonary Embolism always serious?
Severity varies. Some cases are mild, while others need urgent treatment. A clinician assesses symptoms, examination findings and risk factors rather than the name alone.
Can I diagnose this with symptoms alone?
No. Different conditions can cause similar symptoms. Medical examination and selected investigations are needed for a reliable diagnosis.
Will I need hospital admission?
Admission depends on severity, hydration, oxygen, organ function, ability to take treatment at home and the need for close monitoring.
Can I use over-the-counter medicines?
Avoid self-treatment that may hide warning signs or interact with other medicines. Use medicines only after advice, especially if pregnant, older, diabetic or living with kidney/liver disease.
How soon should I follow up?
Follow the interval advised by the treating doctor. Return sooner if symptoms worsen, new warning signs appear or prescribed treatment is not helping.
Can this condition return?
Some conditions are one-time illnesses; others can recur or require long-term control. Prevention and follow-up depend on the confirmed cause.
