Question: I am 69 years old, female, 4' 10", 105 lbs. and have been in excellent health all of my life. I have been married 47 years and have 3 very healthy children. In the past 2 weeks, I have been experiencing flu-like symptoms: nausea, vomiting and weakness. This, in turn, has caused no appetite. I have been trying to keep down energy drinks (Ensure, Emergen-C). Eventually, though, I throw up white foamy liquid. It seems as though the vomit doesn't come from my stomach because it's always white and foamy. Anything I have put in my stomach doesn't come up. The last time I remember having the flu was over 50 years ago and it didn't seem to last this long. I realize, at my age, that my immune system isn't as strong and viruses can take longer to fight. At this stage of my illness, I'm not feeling the nausea as bad but, can only eat a very small portion. I'm left feeling very weak and the feeling of having to throw up goes away as soon as I burp. I can feel myself getting better, slowly. Do you think I should go see a doctor? Thank you, XXXX
