Ever experienced sudden irritation, anxiousness, or other mood swings? It can be due to poor gut health which directly affects the brain. From toxin buildup to poor sleep quality, here are a few ways gut issues can cause sudden mood swings. Tap to know!

Toxin Buildup

When food is not digested properly, the toxins can enter the bloodstream, a condition known as leaky gut, triggering brain inflammation and leading to mood swings.

Gut Stress

When the gut is stressed, it sends distress signals to the brain, making you feel anxious or overwhelmed and leading to mood swings.

Blood Sugar Imbalance

Poor gut health can disrupt nutrient absorption, leading to mood swings, blood sugar imbalance, and sudden energy crashes.

Disrupted Gut-Brain Axis

The gut and brain are linked with each other helping regulate emotions and mood. Poor gut health can make the brain anxious, irritated, and more.

Poor Sleep Quality

An unhealthy gut can disrupt melatonin production (sleep hormone) in the body, leading to poor sleep quality and mood swings.
