[/INST] Thanks for your question on HCM. Get done serum cholesterol level. If this is high then you need to start lipid lowering drugs like statin. And this can reduce fat accumulation on your back. But if your cholesterol levels are normal then liposuction is the only option. It is very safe surgery. It is usually done in day care setting. So no need to worry for this surgery. Success rate is 90% but in 10% cases recurrence is there. So discuss in detail about recurrence with your treating doctor. </s>
