@ognj Welcome to Mayo Clinic Connect! We're always happy to see new members post. Really, it's no bother, and we value what you have to share.

Similar to the drug interactions we see scroll across the bottom of the TV screen during a medication commercial, where we wonder how many people experience "that complication", we can look at different conditions in the same manner, I believe. Not everyone may have the same indications or combinations of symptoms in a given health issue.

If your dad has not had a complete physical examination to uncover possible reasons for his weight loss, fatigues, confusion, and so on, that would be a good start. Our bodies are miracle machines, and all the different systems have to play well together. Results of bloodwork and other tests are then evaluated together and possible concerns can be addressed. For me, a weight loss like that is a big red flag! Confusion can be as simple as the body's response to infection of some kind.

As you wait patiently for the testing to get done, and the results to be filtered back to you, how are you doing, handling this? How is your dad handling these confusing times? Ask away with any questions!
