Signs You Are Caffeine Intolerant: Listening to Your Body


Caffeine is a widely consumed stimulant found in coffee, tea, energy drinks, and various other products. While many people enjoy its stimulating effects, some individuals may experience adverse reactions due to caffeine intolerance. In this blog post, we'll explore the signs of caffeine intolerance, helping you better understand your body's response to this common substance.

  1. Sleep Disturbances

If you find it difficult to fall asleep, experience frequent awakenings during the night, or suffer from restless sleep, caffeine intolerance might be the culprit. Caffeine can disrupt your sleep patterns and make it challenging to get a good night's rest, even when consumed earlier in the day.

  1. Jitters and Anxiety

Feeling excessively jittery or anxious after consuming caffeine is a common sign of intolerance. This heightened state of alertness may be accompanied by a racing heart, trembling hands, and a general feeling of restlessness.

  1. Digestive Discomfort

Caffeine can stimulate the digestive system, leading to stomachaches, acid reflux, or even diarrhea in some individuals. If you experience frequent gastrointestinal discomfort after consuming caffeinated beverages, you may be caffeine intolerant.

  1. Headaches and Migraines

Caffeine withdrawal headaches are well-known, but caffeine intolerance can also trigger headaches and migraines when you consume caffeine. These headaches often occur shortly after ingestion and can be quite severe.

  1. Heart Palpitations

Caffeine is a cardiovascular stimulant, and in caffeine-intolerant individuals, it can cause heart palpitations, which feel like a fluttering or rapid heartbeat. This can be a cause for concern, particularly if you have pre-existing heart conditions.

  1. Increased Blood Pressure

Consuming caffeine can lead to a temporary increase in blood pressure. For those with caffeine intolerance, this rise in blood pressure can be more significant and potentially dangerous, especially if you have hypertension.

  1. Nervousness and Restlessness

Caffeine intolerance can manifest as heightened nervousness and restlessness, making it difficult to relax or concentrate. This can be counterproductive in your daily life and lead to increased stress levels.

  1. Gastrointestinal Disorders

Individuals with irritable bowel syndrome (IBS) or other gastrointestinal disorders may find that caffeine exacerbates their symptoms, leading to abdominal pain, cramps, and irregular bowel movements.

  1. Mood Swings

Caffeine can influence mood, and in caffeine-intolerant individuals, it can lead to mood swings, increased irritability, and even depressive symptoms. If you notice significant changes in your mood after consuming caffeine, it's essential to consider caffeine intolerance as a possible cause.

  1. Increased Urination

Caffeine is a diuretic, meaning it increases urine production. If you find yourself visiting the bathroom more frequently after consuming caffeine, it could be a sign of intolerance.


Understanding your body's response to caffeine is crucial for your overall well-being. If you recognize one or more of the signs of caffeine intolerance mentioned above, it's a good idea to consider reducing your caffeine intake or eliminating it from your diet altogether. By doing so, you can avoid the discomfort and health risks associated with caffeine intolerance, and make choices that better support your individual needs and health. You can still enjoy coffee alternatives such as the delicious Kwush super lattes which can give you the ritual that coffee does without all the negative impacts whilst also boosting your health through functionally beneficial ingredients such as ashwagandha and turmeric.
