Gastrointestinal Issues

GI problems are significantly more common in autistic people.

"For years I thought my stomach issues were anxiety. Getting proper treatment changed my life." — Autistic adult

Common Symptoms

Constipation, diarrhea, abdominal pain, food selectivity, reflux, general digestive discomfort.

Food Selectivity

Strong preferences often related to sensory sensitivities to textures, need for sameness, anxiety around new foods. Common and valid.

Why Often Missed

Interoception: Difficulty recognizing pain or hunger. See Interoception.

Behavioral signs: Discomfort may show as irritability, sleep problems, or withdrawal.

The Gut-Brain Connection

GI issues can affect sleep, mood, and behavior. The gut and brain communicate bidirectionally.

Getting Help

• Document symptoms and patterns
• Consult GI specialist
• Don't accept "it's just autism"
• Work with dietitian who respects sensory preferences

Caution

Avoid treatments claiming to "cure autism" through the gut, unproven supplements, or extreme diets.

GI issues are real, common, and treatable. Proper treatment improves quality of life.
