Which condition is a contraindication for the use of Plenity?

Plenity, a weight management device that expands in the stomach to promote a feeling of fullness, is contraindicated in patients with gastrointestinal structural abnormalities. This is because structural issues, such as strictures, tumors, or any abnormalities that might impede normal gastrointestinal function, could lead to complications. When Plenity expands in the stomach, it relies on a normal anatomical structure to function safely and effectively. If there are structural abnormalities, there could be a risk of obstruction or other serious side effects that could arise from its use.

In contrast, obesity is the condition for which Plenity is designed, and it is not a contraindication. Gastroesophageal reflux disease (GERD) often signifies a need for medical management, but it is not an outright contraindication unless the reflux is severe, and even then, the decision to use Plenity would depend on individual assessment and risks. Similarly, diabetes is commonly managed alongside obesity treatments and does not inherently contraindicate the use of Plenity. Hence, the only clear contraindication among the listed conditions is the presence of gastrointestinal structural abnormalities.
