Unfortunately, you can NOT become a surgeon after Bachelor of Homeopathic Medicine and Surgery or BMHS. Be it a normal MBBS or BHMS, no one is allowed to do surgery right after the bachelors degree.

To become a surgeon, you'll have to do Masters in Surgery, which is a 3-year course. After getting this degree, even a BMHS can become a surgeon.

Hope I have answered your question. All the best!
