What You'll Learn

Alli diet pills can cause liver damage
Alli (orlistat) is an over-the-counter medication used to help people lose weight. It is intended for overweight adults who are also following a reduced-calorie, low-fat diet. Alli works by blocking the intestines from absorbing about 25% of the fat that a person eats. Fats that aren't absorbed leave the body through bowel movements.
However, Alli has been linked to severe liver injury in rare cases. The U.S. Food and Drug Administration (FDA) has identified 13 total reports of severe liver injury with orlistat, with 12 foreign reports of Xenical and one U.S. report of Alli. While a cause-and-effect relationship between orlistat and severe liver injury has not been established, it is important to be aware of the potential risks.
If you are experiencing any of the following symptoms, contact your healthcare provider immediately as they may be signs of liver damage:
- Itching
- Yellow eyes or skin
- Dark urine
- Loss of appetite
- Light-coloured stools
- Lower back or side pain
- Nausea
- Inability to urinate
In addition to liver damage, other rare but serious side effects of Alli include kidney problems, gallbladder problems, and severe allergic reactions. It is important to discuss any current and past health conditions, as well as any medications or supplements you are taking, with your healthcare provider before starting Alli or any other weight-loss medication.

The pills are linked to kidney problems
Alli diet pills are the over-the-counter version of a weight loss drug called orlistat. Orlistat is commonly used to help people with obesity or those who are overweight lose weight. It works by reducing the amount of fat the body absorbs from food, thereby reducing calorie intake.
It is worth noting that Alli diet pills have numerous other side effects in addition to the risk of kidney problems. They can cause digestive problems such as abdominal pain, diarrhea, and flatulence. They can also impair the absorption of fat-soluble nutrients like vitamins A, D, E, and K, leading to nutrient deficiencies. Furthermore, they may interfere with certain medications and cause severe allergic reactions.
Due to these potential side effects, it is crucial to consult a healthcare professional before taking Alli diet pills or any other weight loss supplement. They can help determine if Alli is suitable for you based on your health conditions, medications, and other individual factors. Additionally, it is important to note that Alli should not be taken during pregnancy or by individuals with certain health conditions, such as cholestasis or malabsorption syndrome.

Alli is unsafe for pregnant people
Alli is an over-the-counter medication used to help with weight loss. It is the only FDA-approved weight loss aid available without a prescription. The active ingredient in Alli is orlistat, which works by blocking the absorption of about 25% of fat in the foods consumed.
Alli is also not recommended for people with severe kidney problems, gallstones, or pancreatitis. Orlistat may cause kidney stones and kidney damage that can lead to renal failure. It may also cause gallstones and severe allergic reactions.
In addition, Alli can upset the stomach, especially during the first few weeks of use. These effects include diarrhea, loose and oily stools, and nausea. It is important to follow a reduced-calorie, low-fat diet and get regular physical activity when taking Alli.

The drug may cause gallbladder issues
Alli is a diet pill that is a low-dose version of the prescription-only medication Xenical. Both contain orlistat, which reduces dietary fat absorption in the body. While Alli can help people lose weight, there are several health risks and side effects associated with its use.
One of the potential side effects of taking Alli is that it may cause gallbladder issues. Specifically, taking orlistat, the active compound in Alli, may lead to the development of gallstones, a condition known as cholelithiasis. This is a serious side effect, and individuals who experience any symptoms of gallbladder problems while taking Alli should contact their healthcare provider immediately.
It is important to note that Alli is not suitable for everyone and should not be taken by certain individuals. For example, people with gallbladder issues, such as cholestasis, a problem where bile does not flow well, should not take orlistat. Additionally, those with a history of eating disorders or disordered eating should also refrain from using Alli, as it could indicate or exacerbate these issues.
Furthermore, Alli may interact with other medications and supplements. Therefore, it is crucial to consult a healthcare professional before taking Alli to ensure it is safe and appropriate for your specific health needs. During this consultation, individuals should disclose all health conditions, medications, vitamins, minerals, herbal products, and supplements to their healthcare provider to determine if Alli is right for them.
While Alli may be an effective tool for weight loss for some individuals, it is essential to prioritize overall health and well-being. Combining Alli with a low-calorie, low-fat diet, and consistent exercise regimen may enhance weight loss results. However, it is crucial to adopt healthy habits and commit to a reduced-calorie diet and regular physical activity to achieve sustainable weight loss and improve health outcomes.

It should also not be taken by people with certain health conditions, including malabsorption syndrome, eating disorders, and cholestasis, a condition that impacts the flow of bile from the liver.
It is important to consult a healthcare professional before taking Alli, as it may not be safe for everyone. It is also important to note that Alli is intended to be used in conjunction with a reduced-calorie, low-fat diet and regular exercise. Without these lifestyle changes, Alli will not be effective in helping individuals achieve their weight loss goals.
In addition, there are several side effects associated with Alli. The most common side effects include digestive problems and nutrient deficiencies, including deficiencies in fat-soluble vitamins.
