Boală de reflux gastroesofagian (BRGE)

Eu primesc BRGE: Boală de reflux gastroesofagian, or, GERD (Gastroesophageal reflux disease).

(You can't receive a disease; you can be diagnosed with a disease "eu am primit diagnosticul de BRGE" or you can say that you have a disease already "eu am BRGE"

Am fost cărunt vremelnic, vărsătură și am indispus în trecut. - this doesn't really make sense

carunt=gray-haired, and you can't be gray-haired for a while only; you are or you are not

for the rest of the sentence: "am varsat si am fost indispus" (you already used the past tense, so no need for "in trecut" anymore)

Am încercat să zâmbesc, azi.

"Azi am incercat sa zambesc"

In Romanian: Boală de reflux gastroesofagian (BRGE)
