Cannabinoid Hyperemesis Syndrome (CHS) is a condition that affects some individuals who use cannabis regularly and over a long period. It is characterized by recurring episodes of severe nausea, intense vomiting, and abdominal pain. While the exact mechanisms are still being investigated, chronic cannabis use can disrupt the body’s systems that regulate nausea and vomiting. This article outlines dietary approaches to manage CHS symptoms, focusing on what to eat during acute episodes and for long-term recovery and prevention.
Eating During Acute Episodes
During an acute episode of Cannabinoid Hyperemesis Syndrome, the primary goals are to prevent dehydration and provide gentle nutrition. Hydration is paramount, as continuous vomiting can lead to fluid and electrolyte imbalances. Small, frequent sips of clear liquids such as water, clear broths, or electrolyte-replenishing oral rehydration solutions are recommended.
Once liquids can be tolerated, bland and easily digestible foods should be introduced in small portions. The BRAT diet (bananas, rice, applesauce, and plain toast) is often suggested due to its gentle nature on the digestive system. Other suitable options include plain crackers, boiled potatoes, and plain oatmeal. Avoiding large meals and instead consuming tiny amounts frequently can help minimize stomach irritation and reduce the likelihood of further vomiting.
Diet for Recovery and Prevention
After the acute phase subsides, dietary considerations shift towards restoring nutrition and supporting overall digestive health. Gradually reintroducing a wider range of foods is beneficial, focusing on a balanced diet. This includes whole foods, fruits, vegetables, lean proteins like plain chicken or fish, and complex carbohydrates such as plain rice.
Incorporating foods that are gentle on the stomach and easy to digest, like bone broth and hard-boiled eggs, can help with nutrient replenishment and muscle mass maintenance. Paying attention to individual food sensitivities is important. Keeping a food diary can help identify specific items that might trigger discomfort. The long-term approach emphasizes a diet that supports gut health and helps prevent future episodes by maintaining digestive stability.
Foods and Substances to Avoid
The most significant step in managing and preventing CHS recurrence is complete abstinence from cannabis in all forms, including products containing THC and CBD. Continued use will likely lead to symptom return. Symptoms typically resolve within days to a few months after stopping cannabis use.
Beyond cannabis, several dietary items are commonly reported as potential triggers that can worsen CHS symptoms. These include spicy foods, which can irritate the digestive tract. Fatty or greasy foods, acidic items like citrus fruits and tomatoes, and processed foods. Additionally, chocolate, caffeine (found in coffee, tea, and energy drinks), and alcohol can irritate the stomach lining and potentially induce or exacerbate symptoms.
