3. Ulcers on your mouth
Smoking, allergies, and inflammation are the most common reasons for an ulcer to show up.
On the other hand, if you are experiencing fatigue, dizziness, irregular heartbeat, and muscle weakness, you should check your diet. You might need a boost of vitamin B12, iron, or folate!
4. Peeling nails and cuticles
Peeling nails and cuticles are a sign of iron deficiency. On the other hand, the underactive thyroid, lung disease, or kidney disease might be the cause. Keep up with an iron-rich diet!
