Side Effects of Splenda Sweetener

Updated April 17, 2017

With obesity and sugar consumption at an all-time high, many people have turned to artificial sweeteners, such as Splenda, to replace sugar and lose weight. Splenda can have side effects. For example, it is common for people to be allergic to sucralose, the main ingredient of Splenda.


One possible side effect from Splenda unrelated to allergies is the possibility of chlorine poisoning. Splenda is one of the few artificial sweeteners that claims to be made from sugar; chlorine atoms are added. Ingesting too much chlorine can lead to chlorine poisoning. In most cases, using Splenda won't be harmful because the amount of chlorine is so small, but constant consumption of Splenda could make you sick.


Some people who have consumed Splenda have reported having diarrhoea almost immediately after use. Intestinal cramps, stomach pains and gas are similar side effects that can result from consuming Splenda.


According to Dr. Stuart Stark at Everyday Health, Splenda is one of the most common dietary foods that causes people to have headaches. These headaches could be minor headaches, but they also could be as serious as migraine headaches.

Chest Pains

Chest pains, constricted airways, heartburn and indigestion are side effects that have been reported when consuming Splenda.

Weight Gain

The reason people use artificial sweeteners like Splenda is to avoid sugar and lose weight, but Splenda actually can have the opposite effect. The body does not consider Splenda to be food; the sweetener does not satisfy your body's craving, so your body may tell you to eat even more.
