Hi.
Thanks for your query.
Noted the history about your husband having
lichen planus, started with
constipation then turned into
diarrhea, had been to many Doctors, no help, He is 73 and lost 28 pounds in 3 years. Wants to know whether this is curable or not.
Lichen planus is sort of a immunological disturbance hence can be cured only if the immunology controls the disease which is difficult at the age of 73, although not impossible. He has to take immunity boosters.
Other medical treatment is also available although everything control the disease does not really cure it.
But the Lichen planus can not really reduce the weight at all as this is relatively benign.
Take multivitamins, particularly
Vitamin A and D in therapeutic dosages after blood estimations.
Avoid too hot and too cold things.
Maintain good
oral hygiene.
Consult your Doctors to know the reason of weight loss, there are other more important reasons for this.
