Acceptable methods include double barrier methods, intrauterine device (IUD), postmenopausal status, and/or documentation of surgical sterilization * Participants must have no chronic, clinically severe health issues which, in the opinion of their physician or the research team, could preclude trial activities including the one week drug exposure phase Exclusion Criteria: * History of gastroparesis * History of celiac disease * Inflammatory bowel disease (Crohn's disease, ulcerative colitis) * Microscopic colitis, including collagenous colitis * Has taken linaclotide within 30 days prior to consent * Any malignancy except colorectal cancer or any active radiotherapy or cytotoxic chemotherapy within the last 6 months of baseline. Participants with a history of basal cell or squamous cell skin cancer may be enrolled at the discretion of the investigator * Participants may not be receiving any other investigational agents, or be active participants in any clinical trials. If participants previously participated in a clinical trial, a 30 day washout period for the investigational drug is needed before the participant can be considered for this study * History of allergic reactions attributed to compounds of similar chemical or biologic composition to linaclotide * Uncontrolled current illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements * Pregnant or lactating women * History of bleeding/coagulation problems.
