My father died of PC at 50, so I'm always on the lookout for signs in myself. About 5 years ago I began losing weight slowly. Dr. was not concerned because it was slow, but I've never gained wt back, and even lost some. 2.5 yrs ago she ordered up CT scans followed by 2 more in 2018, and nothing was found. In March 2019 she ordered a NMR scan, and nothing was found. I've had blood tests, most recently in May 2020, with only my RDW a bit high. I also had a small stroke 5.5 yrs ago resulting in some dizziness, which has never gone away. In fact, it's gotten worse–and my energy is almost depleted. I've also had tachycardia, am taking meds for it. Drs keep saying I don't have PC, keep subscribing sertraline for depression as well as heart meds. If I'd gain weight, I'd feel reassured–but I'm not. Bowel habits are a bit unusual, and I have lots of gas. Can anybody suggest a next step for me?
