My 78 year old friend lost her husband recently and has a lot of anxiety issues.  She is not eating well.  She gets nauseous so eats some little something - late Boost - to feel a little better.  She is not eating enough, and not eating the best foods.  She has little or no confidence in her primary doctor.  I think she needs to find a new doctor and get a complete workup.  She is also having a very difficult time with sciatica and is seeing an ortho. but not getting any relief as yet after first taking a round of steroids and now a round of anti-inflammatory pills.  Can nausea be a sign of something worse?  I think she overeats sweets.  She only weighs about 100 pounds, or less.
HI, thanks for using Chat Doctor Grief can result in different symptoms such as headache, loss of appetite, insomnia, fatigue, muscle aches and pains, nausea. The nausea that she is experiencing could be related to her loss, but there are other causes of nausea. The other causes are (1) causes related to the abdomen such as liver disease, HERD, obstruction of the bowel, gall bladder disease(2)metabolic effects-alcohol, high calcium, side effects of some medications(3)central nervous system causes such as migraine, mass Though it can be related to her grief, if the nausea continues she may want to see her doctor for an evaluation. If she does not wish to see this doctor then she can consider another.I hope this helps
