Lab ALK Phosphatase

My number is 241 H  range 38-137 is that anything to worry about?

Your doctor may want to do other tests but this elevated level is likely the stress on your liver from the rapid weight loss - it will right itself once your weight loss slows.

Ditto what Kim said.  Elevated ALK is related to fatty liver and rapid weight loss can cause a high ALK.  It could also be a sign of vitamin D deficiency or Hypothyroidism.  

I have hypothyroidism, my weigh has stayed the same for about 3 months now. I lost 100lbs
