People have begun using green tea as a pill to help them lose weight. Since the extract from the tea, like the tea itself, acts as a stimulant for your central nervous system, it may make you feel less hungry. Many weight loss supplements contain stimulants since they lower the appetite. Green tea, scientifically named camellia sinensis, has not yet undergone an evaluation by the U.S. Food and Drug Administration for safety and efficacy, so it may not produce all the effects its marketers claim. Green tea pills may produce some side effects.
Mental Problems
Green tea weight loss pills, because of their stimulant effects, may induce some mental difficulties common for such stimulants. If you take the pills, you may feel more anxious than you usually do. The supplement also may make you become irritable, Drugs.com indicates. You may feel nervous for no apparent reason. These effects on your mental state classify as non-serious problems, but Drugs.com recommends consulting a physician about them.
Arrhythmia
Stimulants, such as those found in green tea diet pills, may induce an alteration of your regular heartbeat. You may notice your heart begins to beat unusually, meaning it may skip a beat or become irregular. When you experience a side effect that involves how your cardiovascular system works, you should immediately speak with your doctor about it. Any type of arrhythmia may cause dangerous health concerns.
Insomnia and Headaches
If you use green tea diet pills, you may find you cannot sleep. Again, this occurs because green tea stimulates your body's nervous system. This makes it difficult for you to get rest. Stimulants also tend to cause headaches. Both of these side effects should subside as your body adjusts to the supplement. You may lessen the chance of insomnia by taking the pills when you wake, so the stimulant effect has time to wear off by bedtime. Question your physician about either of these problems if you continue to experience them or they feel severe.
