What are the symptoms of a caffeine intoxication?

Caffeine intoxication, also known as caffeine overdose, occurs when you consume too much caffeine. The symptoms of caffeine intoxication can vary depending on the amount of caffeine consumed and individual sensitivity to caffeine. Some common symptoms of caffeine intoxication include:

1. Increased heart rate: Caffeine can cause your heart rate to increase, which can lead to palpitations or a racing heart.

2. High blood pressure: Caffeine can also cause a temporary increase in blood pressure.

3. Anxiety and nervousness: Caffeine can cause anxiety and make you feel restless or jittery.

4. Headaches: Caffeine can cause headaches, especially if you are not used to consuming large amounts of caffeine.

5. Insomnia: Caffeine can interfere with sleep, making it difficult to fall asleep or stay asleep.

6. Upset stomach: Caffeine can cause an upset stomach, including nausea, vomiting, or diarrhoea.

7. Muscle twitches: Caffeine can also cause muscle twitches or tremors.

8. Dizziness: Caffeine can cause dizziness or lightheadedness in some people.

9. Confusion: High levels of caffeine can lead to confusion or disorientation.

10. Dehydration: Caffeine can have a diuretic effect, leading to dehydration if you don't drink enough fluids.

It's important to note that caffeine intoxication can be more severe in people with underlying medical conditions, such as heart disease or anxiety disorders. If you experience severe symptoms of caffeine intoxication, such as chest pain, shortness of breath, or confusion, it's important to seek medical attention immediately.
