IHi I have factor v. On 10mg of coumadin (warfarin). Going thru menopause. Cannot gain weight. Healthy appetite. But weight loss concern. I?

Weight loss. unexplained weight loss should always be investigated, and never ignored. If this is happening to you, you should see your doctor for further evaluation. Have you had a colonoscopy in the last five years? Even with a factor V deficiency, everyone should have colon screening at age 50. See your doctor to look into this. Do not delay. Good luck.
