Hi,
Thanks for posting in HCM.
I understand your concern.
What medication your husband is taking would only control his
gastritis problem. To overcome vomiting, it would be advisable to take Tablet.
Domperidone.
However, his symptoms of
dehydration and cramps in hands and legs needs to be attended to.
His intake of fluids does not alone help to overcome it, as
electrolyte imbalance is not corrected.
Kindly ask home to take citrus fruit juices, tender coconut water and oral rehydration solution (ORS) regularly, which will help to restore electrolytes to normal along with correction of dehydration.
In any instance, he feels giddy or weak, you need to seek medical attention promptly as he could be having dehydration induced
hypotension. Such cases needs to be managed by instituting IV fluids.
Hope the information provided would be helpful.
All the best.
