Digestive / GI
Acid Reflux / GERD
A burning sensation in the chest or throat caused by stomach acid flowing back into the esophagus. Worsened by certain foods, large meals, exercise timing, and some supplements.
Bloating
Abdominal distension or uncomfortable fullness caused by excess gas production, gut dysbiosis, food sensitivities, or rapid dietary changes. Worsened by introducing new fiber sources or certain supplements.
Constipation
Infrequent, difficult, or incomplete bowel movements. Common during low-fiber dietary phases, dehydration, or low-carb diets where food volume is reduced significantly.
Diarrhea
Frequent, loose, or watery stools resulting from GI tract irritation, osmotic effects from supplements, dietary changes, or medication side effects. A common early side effect of several health optimization protocols.
Gut Dysbiosis Symptoms (mixed GI)
An imbalance in the gut microbiome characterized by bloating, gas, irregular bowel habits, food sensitivities, and systemic inflammation. Reflects disruption of beneficial bacterial populations.
Loss of Appetite
Reduced desire to eat, which may be intentional (medication-induced) or an unwanted side effect of supplements, fasting, or illness. Can affect nutritional adequacy and muscle retention.
Nausea
An unpleasant sensation of stomach discomfort with urge to vomit. In a health optimization context, commonly triggered by supplements taken on an empty stomach, GLP-1 medications, aggressive fasting protocols, or new dietary changes.
