Nothing is visible to the naked eye.
Are there any other symptoms? Nausea, pain, food intolerances... what's her bowel movement like usually?
She deals with low blood pressure, so most issues pop up when it gets too hot. Medication-wise, she doesn't take anything except an occasional antihistamine for pollen allergies. Stools are generally normal, though they were soft on the day the sample was taken. Hemoglobin is 40.
You can't get a precise diagnosis without testing. It doesn't seem like an emergency, though there are never any guarantees. If she isn't feeling worse or experiencing severe symptoms, she could head out on vacation. But once she's back, she needs to schedule those follow-up tests immediately.
Just watch out during high temperatures or physical exertion—low blood pressure combined with anemia is a nasty cocktail. She needs to make sure she's eating enough, including salt, and staying hydrated!
It would be a good idea for her to eat red meat regularly—it’s the best way to absorb iron.
If she struggles with heartburn, she should avoid coffee and acidic foods, especially on an empty stomach. A probiotic (ask at a pharmacy for capsules, or just stick to things like Acidophil or Bioactive... just remember those "yogurts" are acidic, so don't have them on an irritated stomach) will help with stool quality, along with plenty of fiber (grains, fruit, raw veggies...).
