Dietary fiber is one of the dominant compositions of blueberries. Overeating this fruit will get too much of this fiber into your body system. Too many fibers can be detrimental to human health.

Consuming too many blueberries can cause excess vitamin K in your body. So, it is best to regulate blueberries’ intake to avoid excess vitamin K’s side effects. Too much vitamin K can result in some uncomfortable symptoms. It can lead to conditions like shortness of breath and irregular breathing.

It causes internal bleeding by interfering with some anticoagulant medicine. It is best for individuals on anticoagulant medication to stay away from blueberries. 

3. Vulnerability to Hypoglycemia 

Blueberries are not in any way suitable for individuals who have diabetes. This fruit lowers blood sugar level. The number of blueberries ingested will determine how much it will lower blood sugar.

It can also lead to excessive hunger, pale skin, and erratic mood swings. But, moderate consumption of blueberries is helpful for diabetic patients. It can steadily release sugar into the bloodstream without causing a spike. 

Too many blueberries, on the other hand, has a counter effect. It pushes the body sugar to a dangerously low level. So, it is best to seek professional medical advice if you have diabetes. 

4. Salicylate Sensitivity (in Vulnerable Individuals)

Salicylate is a significant component of blueberries. It is an active ingredient in aspirin, a drug useful for providing pain relief. Aspirin is also a valuable remedy for conditions like fever and inflammation. 

It is best for individuals who are sensitive to salicylate to stay away from blueberries. This fruit contains a high amount of salicylate that can trigger reactions. Some symptoms of this reaction include rashes, diarrhea, bloating, and acid reflux. It can also include headaches and nausea. These side effects can occur even when you consume blueberries in small quantities (if you are sensitive to salicylates). 

5. Aggravates Stone Fruit Allergy 

Allergies are not common with blueberries. Although most people tolerate this fruit, it can cause sensitivity to stone fruits. Examples of stone fruits include cherries, plums, nectarines, and peaches. If you are sensitive to any of these fruits, you might be susceptible to blueberries too. 

6. Poses Risks to Pregnant Women

Blueberries are one of the consumables you should put under check before surgeries. This fruit contains a high level of salicylates.
