1. Flatus / Intestinal Gas

Barley is a good source of dietary fiber (1). This may cause intestinal gas or flatus (2). The reason behind it is the activities of the beneficial bacteria present in our colon. So, try to limit your barley water intake to prevent gas formation.

2. Stomach

Excessive consumption of barley water may upset the stomach. Barley water can also interact with certain medications leading to stomach upset. In both cases, the stomach irritation can come with minor to major symptoms like pain, cramps, bloating, and sometimes even loose bowels or diarrhea and worsen other IBS symptoms (3).

3. Constipation

If you drink too much barley water, the chances are that you will end up developing chronic constipation. Make sure that you consult your physician in case the problem continues for more than 7 days at a time.

4. Rectal Bleeding

In severe cases of constipation, you might experience rectal bleeding with acute pain. Try to avoid consuming this natural laxative in bulk to avoid such situations.

5. Fungal Contamination

It has been reported that barley water can lead to fungal contamination from time to time. Certain contaminants found in the malt extract are Trichothecium Roseum and Ochratoxin A (4), (5). These toxins can take a toll on our bones by breaking them down.

6. Allergic Reactions

Or else, you might experience a number of symptoms like rashes, inflammation, hives, irritation as well as swelling of eyes, eyelids, nose, arms, legs, and even anaphylaxis.

7. Bakers’ Asthma

The grain of barley can cause a serious respiratory allergy called ‘bakers’ asthma’ (6). People working in bakeries are prone to this condition. But you can also fall prey to it if you are exposed to lots of barley flour while preparing your barley water. So, be careful.

8. Blocked / Ruptured Esophagus

Being loaded with fiber, barley can harm your esophagus too. Whenever preparing your drink, make sure that you add enough water to the extract of the malt. Otherwise, you may face difficulty in swallowing, which can eventually block or even rupture your esophagus.

9. Celiac Disease

Celiac disease is basically wheat allergy, which is caused due to gluten intolerance (7). Barley contains a huge amount of gluten, thereby making the condition even worse.

10. Reduced Blood Sugar

Overconsumption of barley water can reduce the amount of sugar in your bloodstream (8). If it goes under the normal level, you will develop hypoglycemia. So, try to keep a close eye on your blood sugar level while drinking barley water regularly.

11. Surgical Complications

As barley water can cause a sudden fall in your blood glucose levels (9), you should always take precautions prior to undergoing surgery. It is recommended that you stop having the drink at least 10 to 14 days before going under the knife. It may help you regulate your blood sugar level so that you can keep all sorts of surgical complications at bay.
