Welcome to the forum.
Very good advice from bsmsl.
Check for other symptoms related to low zinc levels.
Diminished smell and taste, white spots or lines on nails, brittle nails, mouth sores,
dry or cracked skin, weakened immune system.
Should your diet not include foods containing adequate zinc, that would indicate low zinc also. Best sources are red and white meat, seafood, salmon and dairy.
Vegetarian sources are not absorbed well unfortunately.
