What are signs your gut health is poor?

Poor gut health can show up in several ways. Digestive symptoms are the most obvious, including frequent bloating, gas, constipation, diarrhea, heartburn, or stomach pain. You might also notice that certain foods consistently cause discomfort or that your bowel habits are irregular. Beyond digestion, poor gut health can affect your whole body. Fatigue, brain fog, and difficulty concentrating are common signs, as the gut and brain are closely connected. Frequent illness or slow recovery suggests a weakened immune system, which is largely regulated by the gut. Skin issues like eczema, acne, or rashes can also reflect gut imbalances. Unexplained mood changes, anxiety, or depression may also be linked, since the gut produces a significant portion of the body's serotonin.
