Serious Side Effects of Barley Water: What You Need to Know
Barley water, a traditional beverage widely regarded for its hydration and nutrition properties, is often consumed for its touted health benefits. While it is rich in vitamins, minerals, and fiber, regular or excessive consumption may lead to several adverse effects—especially for certain groups of people. This article comprehensively covers the potential side effects, risks, and essential precautions you should be aware of before making barley water a regular part of your diet.
What Is Barley Water?
Barley water is a drink made by boiling barley grains, straining the mixture, and sometimes adding other ingredients such as sweeteners or lemon. It is popular in many parts of the world, especially in Asian cultures, and is valued for its mild flavor and potential health advantages. Yet, like any nutritional supplement or herbal remedy, barley water is not free from side effects.
Who Should Be Cautious With Barley Water?
- People with gluten intolerance or celiac disease
- Individuals prone to food allergies, especially cereal grain allergies
- Those with digestive sensitivity to fiber-rich foods
- Patients taking certain medications
- Pregnant and breastfeeding women (in large amounts)
Main Side Effects and Risks of Barley Water
1. Digestive Discomfort
Barley water is high in dietary fiber, which, while beneficial in small to moderate amounts, can cause significant gastrointestinal issues if consumed excessively. Potential symptoms include:
- Bloating and gas
- Stomach cramps
- Constipation (in rare cases)
- Diarrhea (especially if unstrained or consumed in large quantities)
- Feeling of fullness or discomfort
These adverse effects are typically experienced by those unaccustomed to high-fiber foods, or when large quantities of barley water are consumed daily.
2. Allergic Reactions
Barley is a common allergen among those with cereal grain allergies—especially if you already react to wheat, rye, oats, or similar grains. Allergic reactions can range from mild symptoms to severe, life-threatening complications.
- Symptoms may include:
- Skin itching, hives, or rashes
- Swelling of the lips, mouth, or face
- Difficulty breathing
- Watery eyes and sneezing
- Severe cases: Anaphylaxis (a medical emergency)
Those with confirmed cereal grain sensitivities should avoid barley and barley water entirely.
3. Gluten Intolerance and Celiac Disease
Barley naturally contains gluten, a protein that triggers reactions in people with celiac disease or non-celiac gluten sensitivity. For these individuals, even small amounts of barley water can result in:
- Severe digestive discomfort (nausea, bloating, diarrhea)
- Autoimmune reactions
- Malabsorption of nutrients over time
If you have celiac disease, barley water should be strictly avoided.

4. Potential Weight Gain
Although barley water can support weight management due to its fiber content and ability to promote satiety, it can also contribute to weight gain in certain scenarios:
- If prepared with added sugars or sweeteners
- When consumed in excessive quantities
- Caloric intake can increase if fruit juices, honey, or other flavorings are mixed in
Monitoring your total calorie intake and the portion size of barley water is key to avoiding this risk.
5. Possible Drug Interactions
Barley (and its water) is known to help lower blood sugar levels. This can be beneficial for many, but for individuals taking glucose-lowering medications such as those for diabetes, it might lead to hypoglycemia (dangerously low blood sugar). Additionally, barley may interfere with certain medications when taken in large amounts.
Before adding barley water to your routine, consult a healthcare provider if you:
- Have diabetes or are on insulin/blood sugar-lowering medications
- Are scheduled for surgery soon (potential blood sugar fluctuations)
- Take medications affected by dietary fiber absorption
6. Potential Contamination with Gluten
Using unhulled barley may increase the risk of gluten cross-contamination. If gluten needs to be avoided, always purchase certified gluten-free barley products or seek alternatives. Unintentional gluten exposure may provoke significant health issues in sensitive individuals.
7. Side Effects in Specific Populations
| Population | Precaution/Side Effect |
|---|---|
| Pregnant Women | Safe in food amounts, but higher doses/larger quantities unconfirmed. Avoid barley sprouts in excess. |
| Breastfeeding Women | Stick to food-level intake. High medicinal doses not well studied. |
| Patients with Kidney Disease | May need to avoid added lemon or lemon peel depending on potassium restrictions. |
| Children | There is limited data. Stick to modest, supervised amounts if given. |
8. Allergic Reactions from Skin Application
Although less common, topical application of barley (used in masks or poultices) can sometimes cause skin irritation or allergic reactions, especially in those sensitive to cereal grains.
9. Disturbed Hydration and Electrolyte Balance
Consuming large amounts of barley water as a replacement for plain water may alter your fluid and electrolyte balance. In some rare cases, this could lead to dehydration or an imbalance in essential electrolytes, especially if the beverage is consumed exclusively without enough plain water.
Special Note: Acrylamide in Barley Tea
While barley tea is distinct from barley water, both are prepared from barley grains. Barley tea in particular may contain small amounts of acrylamide, a potentially harmful compound formed during high-heat roasting. Although research is ongoing, it is considered best practice to roast barley thoroughly (to a deep brown) before brewing tea—this reduces acrylamide levels.
Precautions Before Drinking Barley Water
- Consult with a physician if you have existing health conditions (allergies, gluten intolerance, diabetes, kidney issues)
- Ensure barley is sourced from a reputable supplier and properly hulled, especially if gluten-sensitive
- Introduce barley water slowly to observe how your body reacts, especially regarding digestion
- Avoid adding large quantities of sweeteners or flavorings that can bump up the calorie content
- If pregnant, breastfeeding, or preparing for surgery, consume only food-level amounts and seek medical advice if uncertain
Who Should Avoid Barley Water?
- Anyone diagnosed with celiac disease or confirmed gluten intolerance
- People with documented barley allergy or allergies to similar cereal grains
- Patients who must restrict dietary fiber due to gastrointestinal diseases
- Those at risk for hypoglycemia (diabetics on medications)
- Individuals scheduled for surgery in the near future (potential blood sugar impact)
Barley Water: Safe Consumption Tips
- Drink barley water in moderation—limit to one to two servings per day unless under medical supervision
- Always rinse and cook barley thoroughly before use
- Avoid if you notice any allergic reactions or persistent digestive symptoms
- If sensitive to potassium, avoid adding lemon or citrus zest
- Children, pregnant, or breastfeeding women should stick to traditional food-based consumption and avoid supplements
Barley Water vs. Barley Tea: Key Differences and Risks
