||All of the symptoms listed on this page may be caused by something other than sucralose consumption. Be certain to speak with your physician to discuss your symptoms and to get treatment for allergies, illnesses, diseases, or conditions that require medical attention.
Having clarified that, based upon the more than 500 stories received from our visitors, we have compiled a list of the most frequently reported symptoms resulting from the use of sucralose (Splenda). The list, expanding almost monthly, may not contain your particular symptom. That does not mean you aren't suffering side effects from Splenda consumption, but may mean that the side effect has not been reported often enough for us to add it to the list (yet).
- abdominal pain
- gas, sometimes painful
- migraines (severe headaches)
- heart palpitations (fluttering, irregular heartbeats)
- shortness of breath
- anxiety and panic attacks
- spaced-out or drugged sensation
- joint pain, especially in the knees
In addition, the following side effects are being reported more often, although not with the same degree of frequency as those above:
- lone atrial fibrillation
- extreme fatigue
- muscle weakness
- tingling mouth or tongue
- tingling in fingers and hands
- numbness in the lips and tongue
- swollen lips or tongue
- swollen face
- redness or welts on face
- mouth sores
- blurred vision
If you believe you are suffering ill effects after consuming Splenda, we strongly suggest you conduct the two-week test:
For two weeks, double-check every package label (from bottled waters to OTC medications) to ensure you consume absolutely nothing with Splenda (sucralose). Not every product containing sucralose will display the now-familiar Splenda logo, so read every label. If, during the two-week period your symptoms stop and don't return, try consuming something with Splenda as you did previously. If the symptoms return, you've likely discovered the source of your illness. If the symptoms don't abate, worsen, or do not return with a return to Splenda consumption, you may have another illness or problem. In either case, be certain to speak with your physician and discuss your suspicions about sucralose as it relates to your condition.
