The most common gastrointestinal side effects include: Nausea : Reported in 15-44% of patients (higher rates at Wegovy 2.4 mg), typically most pronounced during dose escalation Diarrhea : Affects approximately 8-30% of users, ranging from mild to moderate severity Vomiting : Occurs in 5-24% of patients (higher rates at Wegovy 2.4 mg), often associated with rapid dose increases Abdominal pain : Experienced by 5-20% of patients, usually described as cramping or discomfort Constipation : Paradoxically affects 3-24% despite the medication's effects on motility Dyspepsia and gastroesophageal reflux : Related to delayed gastric emptying These effects result from semaglutide's pharmacologic action on GLP-1 receptors throughout the gastrointestinal tract
This allows triggering of signaling pathways that are critical for maintaining a dynamic balance between stimulating and inhibitory effects exerted upon processes of brain development, synaptic plasticity, and brain regeneration after damage
chemical : A substance formed from two or more atoms that unite (bond) in a fixed proportion and structure

Likewise, energy metabolism and appetite regulation could be altered in a therapeutic direction ( The rationale for dual-receptor agonists for GLP-1 and GIP In healthy volunteers, infusions of GLP-1 and GIP had additive effects on the stimulation of insulin secretion ( In vitro receptor binding studies explored structural requirements for GLP-1 and GLP-1/GIP chimeric peptides regarding their affinity towards the GLP-1 receptor in insulinoma cell lines ( Figure 1 gives an overview of the physiological actions of GLP-1 and GIP on various organ systems ( Table 1 ( Figure 1 Table 1 Effects of GIP receptor agonism or antagonism on glycemic control, body weight, and energy balance in animal models of obesity and diabetes (modified according to Campbell and Nauck) ( Prevention of diet-induced obesity: healthy, nonobese animals at baseline receiving experimental treatment while receiving a high-fat diet
