Check for Zinc Deficiency if You Are Losing Your Sense of Smell. Zinc, an essential trace mineral, is required to produce an enzyme called carbonic anhydrase (CA) VI, critical to taste and smell, which is why loss of sense of smell is one of the classic signs of chronic zinc deficiency.
Some problems with smell only last for a short time and may be due to: 1  A cold or flu that causes a stuffy nose that blocks your sense of smell. The ability to smell will come back when youâre better. 2  Allergies that block your sense of smell. Try to avoid things youâre allergic to, like pollen and pets.
