Alli works by blocking about 25% of the fat you consume from being absorbed in your intestines. This fat is then eliminated through your bowel movements.
How Alli Affects Your Body
This mechanism, while seemingly straightforward, can lead to side effects. The unabsorbed fat can cause oily spotting, loose stools, and more frequent bowel movements. The severity of these side effects varies greatly among individuals, and depends on factors such as your diet and overall health.
Potential Risks and Precautions
Before starting Alli, consult your doctor. Alli is not suitable for everyone. Individuals with certain medical conditions, like gallbladder disease or who take certain medications (e. g., blood thinners), should avoid it. Pregnancy and breastfeeding are also contraindications.
| Oily spotting | Common | Reduce fat intake; consider taking Alli with a meal lower in fat. |
| Loose stools | Common | Increase fiber intake; stay hydrated. |
| Abdominal cramping | Less common | Reduce fat intake; consider taking Alli with a lower-fat meal. |
| Rectal bleeding | Rare | Discontinue use and consult a doctor immediately. |
Dietary Considerations
To minimize side effects, gradually introduce Alli into your routine. Focus on a balanced, low-fat diet, rich in fruits, vegetables, and whole grains. Adequate hydration is also crucial. Remember, Alli is a tool to aid weight loss, not a replacement for healthy lifestyle choices.
