Doctors put "MD" (Doctor of Medicine) after their name to signify they've earned a professional medical degree, indicating extensive training in diagnosing, treating, and prescribing, distinguishing them as fully licensed physicians, similar to "DO" (Doctor of Osteopathic Medicine) for osteopathic doctors, both holding equivalent licensure to practice medicine. It's a credential showing completion of medical school, residency, and board exams, allowing patients and colleagues to quickly understand their qualifications.

What is the lowest rank of doctors?

The lowest rank of a doctor in training is typically an Intern, who is a medical school graduate in their first year of residency, requiring supervision; below them are medical students, and then foundation doctors in some countries like the UK, who are provisionally registered after medical school.

Neither an OD (Optometrist) nor an MD (Medical Doctor) is inherently "better"; they are different types of doctors with distinct training and scopes, with MDs often having broader surgical/specialty training and ODs focusing on vision care, though both diagnose and treat patients, with the best choice depending on your specific health needs and philosophy of care. MDs (and DOs) practice allopathic medicine (treating disease), while ODs (optometrists) focus on eye health, but some MDs also have eye training (ophthalmology), while DOs offer holistic care with manipulative techniques. 

What does MD behind a doctor's name mean?

Which is best, MD or MS?

Your decision should align with whether you prefer diagnosing and treating with medicine (MD) or performing procedures (MS).
