In the UK, diet pills can be prescribed by doctors or purchased over-the-counter. Common options include Orlistat (available on the NHS), which reduces fat absorption, and appetite suppressants like Phentermine. The use of diet pills should always be monitored by healthcare professionals to avoid potential side effects or misuse.

Common drugs for gastritis include proton pump inhibitors (PPIs) like omeprazole, which reduce stomach acid, and H2 blockers like ranitidine. Antibiotics are prescribed if the gastritis is caused by a bacterial infection, such as H. pylori.

A pre-surgery diet prepares the body for bariatric surgery, typically focusing on reducing liver size and overall fat to make the procedure safer. This high-protein, low-carbohydrate diet often lasts for 1-2 weeks before surgery. Patients must follow a strict plan of liquids and protein shakes to shrink the liver and facilitate surgery.

The "Skinny Pen" refers to a weight-loss medication called liraglutide (brand name Saxenda) that is administered through a daily injection. It works by mimicking a hormone that regulates appetite, helping patients feel fuller for longer. This treatment is often used for individuals who struggle with obesity but are not candidates for surgery or who need additional help in managing their weight post-bariatric surgery. The drug is available by prescription and is used in conjunction with diet and exercise.

The stomach sleeve diet follows the same principles as the gastric sleeve diet. After the surgery, patients must follow a structured eating plan, starting with liquids and progressing to solid foods over several weeks. The diet focuses on small, high-protein meals to support weight loss and ensure adequate nutrition.
