Eating smaller meals, staying hydrated, and making small lifestyle adjustments can help reduce discomfort
Mechanisms of L-cell GLP-1 secretion Physiologically, L-cells, which are most common in the distal parts of the intestines [15], are stimulated to secrete all their secretory products (GLP-1, GLP-2, gut-derived glucagon [also called glicentin], peptide tyrosine tyrosine, oxyntomodulin) in response to nutrient ingestion [16, 17]

Gastrointestinal side effects are by far the most prevalent during early treatment: Nausea Very common (may affect more than 1 in 10 people), typically peaking during the first week and often improving over two to four weeks [1] [2] Vomiting Common (may affect up to 1 in 10 people), usually occurring alongside nausea [1] [2] Diarrhoea Common, may persist for several weeks Constipation Common, sometimes alternating with diarrhoea Abdominal pain or discomfort Common, ranging from mild cramping to more pronounced discomfort Dyspepsia (indigestion) Common Eructation (belching) Common Reduced appetite A therapeutic effect that may feel uncomfortable initially, affecting eating patterns These symptoms arise because semaglutide mimics the natural GLP-1 hormone, which slows gastric emptying and increases satiety

Practical options when cost is the concern If price is what drives the search, options include manufacturer savings-card programs for eligible commercially insured patients, pharmacy discount platforms such as GoodRx and SingleCare, asking a provider about a patient assistance program, compounded semaglutide or tirzepatide through a licensed pharmacy where clinically justified, and the PlexusDx Weight Management Protocols, which offer Tirzepatide Injection and Tirzepatide Oral at published per-protocol pricing
Eat Enough Protein Protein is the building block of muscle, and it becomes even more important when appetite decreases (as often happens during GLP-1 therapy)
