14 Signs Your Anxiety Might Be Masking a Bigger Health Issue

7. Nutritional Deficiencies That Cause Anxiety Symptoms

What you eat (or don’t eat) plays a major role in anxiety regulation. Deficiencies in key nutrients like vitamin B12, vitamin D, magnesium, and zinc have been linked to increased anxiety, irritability, and fatigue. Magnesium, in particular, helps regulate the nervous system, and a deficiency can lead to muscle tension, restlessness, and panic attacks. Eating a balanced diet rich in whole foods, or supplementing if needed, can improve both mental clarity and emotional stability.

8. The Link Between Anxiety and Substance Use

Some people unknowingly use alcohol, caffeine, or recreational drugs as a way to cope with anxiety, only to find that these substances make symptoms worse over time. Excessive caffeine can overstimulate the nervous system, leading to jitteriness and panic attacks, while alcohol can disrupt brain chemistry and worsen anxiety. Substance-induced anxiety often creates a dependency loop—using substances for temporary relief but experiencing heightened anxiety afterward. Reducing stimulant intake and exploring healthier stress-management techniques can help break this cycle.
