| name | Dietary Fiber |
| classification | Dietary supplement, not a traditional drug. |
| pharmacokinetics | Dietary fiber is not absorbed systemically. It passes through the gastrointestinal tract and is largely fermented by gut bacteria. No specific pharmacokinetic data exists as it is not a traditional drug. Effects are primarily related to its impact on gut transit time and colonic metabolism. |
| suggested dosage | Recommended daily intake varies depending on age, activity level, and health. A general guideline is 25-30 grams per day for adults. Consult a registered dietitian or nutritionist for personalized recommendations and to address individual health needs. Do not dramatically increase fiber intake suddenly, as this can cause gas, bloating, and diarrhea. |
| indications | | 1 | Promoting regularity | | 2 | Improving digestive health | | 3 | Controlling blood sugar levels (soluble fiber) | | 4 | Managing cholesterol levels (soluble fiber) | | 5 | Promoting satiety and weight management (insoluble and soluble fiber) | | 6 | Reducing risk of certain chronic diseases (e.g., heart disease, type 2 diabetes, colon cancer) |
|
| safety in pregnancy | Generally considered safe in moderate amounts, but consult a healthcare professional for individual needs and conditions. |
| safety in breastfeeding | Generally considered safe in moderate amounts, but consult a healthcare professional for individual needs and conditions. |
| side effects | | 1 | Gas | | 2 | Bloating | | 3 | Diarrhea (especially with sudden increased intake) | | 4 | Constipation (rarely, especially with low fiber intake) | | 5 | Potential interaction with certain medications (see interactions) |
|
| alternatives | |
| contraindications | | 1 | Severe gastrointestinal conditions (e.g., severe IBD, recent abdominal surgery) - consult a medical professional. | | 2 | Intolerance to specific types of fiber (e.g., plant fiber sensitivities). | | 3 | Extremely high fiber intake may interfere with absorption of some nutrients, but this is less problematic at recommended levels. |
|
| interactions | | 1 | Certain medications (e.g., some anti-diarrheal medications, iron supplements, or thyroid medication) - consult a healthcare provider about potential interference. | | 2 | Fiber may interact with some medications, affecting their absorption and potentially modifying their effects. This is most relevant to certain prescription drugs. |
|
| warnings and precautions | | 1 | Gradually increase fiber intake to prevent digestive upset. | | 2 | Drink plenty of water to aid digestion. | | 3 | Be aware of potential individual sensitivities. | | 4 | Consult a doctor or registered dietitian if there are existing health conditions or digestive concerns. | | 5 | Avoid extremely high amounts of fiber without professional supervision. |
|
| additional information | | 1 | Various types of fiber exist (soluble and insoluble). Different types have different effects on the body. | | 2 | Food sources include fruits, vegetables, whole grains, legumes, and nuts. | | 3 | Fiber supplements are available; however, consuming fiber from whole foods is generally preferred. |
|
| patient specific notes | | age | 25 | | weight | 70 | | additional info | For a 25-year-old male weighing 70 kg, a balanced diet rich in whole foods is likely optimal. A registered dietitian can provide personalized dietary recommendations. |
