Stevia is a natural, nonsugar sweetener derived from the Stevia rebaudiana plant. Its use is particularly beneficial for people who are trying to lose weight or have diabetes, as stevia contains no calories and doesn't affect blood sugar levels like other kinds of natural sweeteners. Despite these benefits, there are side effects and potential drawbacks to using stevia that should be discussed with your health care provider.
Side Effects
Typically, using stevia is not associated with unpleasant side effects. Stevia contains a compound called stevioside, which may cause nausea or abdominal bloating, leading to a temporary decrease in appetite. You may also experience unusual sensations of numbness, dizziness or muscle pain after using stevia. Such side effects are typically temporary and usually subside within a few hours of consuming stevia. If your side effects persist or become severe, consult your physician for further evaluation and care.
Hypersensitive Reaction
If you are allergic to chrysanthemums, daises, marigolds, ragweed or any other plant member of the Asteraceae/Compositae family, you may be at risk of experiencing a hypersensitive reaction upon exposure to stevia. Mild allergic reaction symptoms may include oral itching, skin rash or hives. A severe allergic reaction to stevia may be life-threatening. Its symptoms may include facial swelling, difficulty breathing, weakness or loss of consciousness. Contact your doctor immediately if you experience any type of hypersensitivity reaction after handling or consuming stevia.
Drug Interactions
Inform your doctor of any medication you are taking before you begin using stevia. Certain drugs should not be taken in conjunction with stevia. If you are on any medication for diabetes, consult your doctor before using stevia. Stevia can lower your blood sugar, which may enhance the effects of your diabetes medications and put you at risk of developing hypoglycemia, or severely low blood sugar. Concomitant use of blood-pressure-lowering medications and stevia may result in a significant reduction in your blood pressure. Additionally, avoid using stevia if you are taking lithium. This combination may make it harder for your body to metabolize lithium and may cause this medication to build up in your body.
Contraindications
Always let your doctor know of any health problems you may have before using any new medication or herbal treatment, including stevia. Women who are pregnant or breastfeeding should avoid consuming stevia, as the safety of using this sweetener during pregnancy is unknown.
