Understanding the Need for Thickened Water
As people age, some experience dysphagia, a condition characterized by difficulty swallowing. This can be caused by various factors, including stroke, neurological disorders like Parkinson's disease, or general weakening of the swallowing muscles. For individuals with dysphagia, thin liquids like water can move down the throat too quickly, entering the airway and lungs (a process called aspiration). This can lead to serious health issues, including aspiration pneumonia. Thickening water makes it move more slowly, giving the person more time to control the swallow and direct the liquid safely into the esophagus.
The International Dysphagia Diet Standardisation Initiative (IDDSI)
To ensure consistency and safety, healthcare professionals use the IDDSI framework to classify food and drink textures. It's crucial to consult with a speech-language pathologist (SLP) to determine the appropriate thickness level for an individual's specific needs.
- Level 1: Slightly Thick: A little thicker than water and can be sucked through a standard straw easily.
- Level 2: Mildly Thick (Nectar-like): The consistency of fruit nectar or a thick milkshake, able to be sipped from a cup but with more effort required through a straw.
- Level 3: Moderately Thick (Honey-like): Flows slowly and may require a spoon or wide straw.
- Level 4: Extremely Thick (Pudding-like): Not drinkable from a cup and must be eaten with a spoon.
How to Thicken Water with Commercial Thickeners
Commercial thickeners are widely available and come in powder or gel form. They are typically tasteless and designed to mix smoothly into liquids without altering the flavor. Always follow the specific instructions on the product's packaging, as ratios can differ between brands.
Powder Thickeners (Starch-based)
Brands like Thick-It and Thick & Easy are examples of starch-based powders.
- Measure: Follow the product's guidelines for the correct powder-to-water ratio based on the desired consistency (e.g., nectar or honey-thick).
- Mix: Add the measured powder to the water while stirring vigorously with a fork or whisk.
- Wait: Allow the mixture to stand for a few minutes to reach its final thickness, as starch-based thickeners may continue to thicken over time.
Gel Thickeners (Gum-based)
Products such as SimplyThick are gum-based gels that often result in a more stable consistency that doesn't change over time.
- Measure: Add the recommended amount of gel thickener to the water.
- Mix: Stir or shake vigorously for about 30 seconds until fully dissolved.
- Serve: The liquid is ready to serve immediately, as gel thickeners do not continue to thicken over time.
How to Thicken Water with Natural Ingredients
For a more natural approach, certain household ingredients can be used to thicken water or other liquids. However, these methods can be less precise and may alter the taste or texture more significantly than commercial options.
- Baby Rice Cereal: A small amount can be stirred into water until the desired thickness is achieved. This works well for hot liquids.
- Pureed Fruits: Blending pureed fruits like bananas or applesauce into water or juice can naturally thicken the liquid while adding flavor.
- Cornstarch: For hot liquids, a cornstarch slurry can be created and added. The liquid will thicken as it heats.
- Instant Potato Flakes: These can be added to broths or water to achieve a thicker consistency.
Important Safety Considerations
Caregivers must exercise caution when preparing and serving thickened liquids to ensure the safety and well-being of the elderly individual. Proper training and communication with healthcare providers are essential.
- Consult a Speech-Language Pathologist (SLP): An SLP assessment is vital to determine the appropriate thickness level and whether thickened liquids are the right intervention.
- Prevent Dehydration: Thickened liquids can sometimes lead to reduced fluid intake because they can be less palatable and make a person feel full faster. Always monitor fluid intake closely to prevent dehydration.
- Watch for Inconsistencies: Some thickeners continue to thicken over time, while others don't. Be vigilant about checking the consistency before serving, as an improperly thickened liquid can be just as dangerous as a thin one.
- Avoid Melting Foods: Foods like gelatin, ice cream, and sherbet melt into thin liquids and should be avoided.
- Medication Administration: Taking medications with thickened liquids can affect how they are absorbed by the body. Always consult a pharmacist or doctor to understand potential drug interactions.
- The IDDSI Flow Test: This standardized test uses a 10 mL syringe to measure how much liquid flows through in 10 seconds, helping ensure the correct thickness level is consistently achieved.
Comparison of Thickeners
| Feature | Starch-Based Powder (e.g., Thick-It) | Gum-Based Gel (e.g., SimplyThick) | Natural Ingredients (e.g., Cereal) |
|---|---|---|---|
| Consistency | Can become thicker over time. | Remains stable over time. | Inconsistent; can clump and alter texture. |
| Taste/Texture | May leave a grainy texture and starchy aftertaste. | Less likely to have a grainy texture. | Can significantly alter the taste and mouthfeel. |
| Mixing | Requires brisk stirring and setting time. | Mixes quickly and can be served immediately. | Varies widely; can be more labor-intensive. |
| Cost | Generally more affordable. | Typically more expensive. | Can be very inexpensive, using pantry staples. |
| Best For | General use, but requires careful timing. | Situations requiring stable viscosity, such as for slow drinkers. | Caregivers seeking a budget-friendly or flavor-adding option. |
The Free Water Protocol
Some patients, particularly those with strong preferences and lower risk factors, may be candidates for a "Free Water Protocol." This allows for the consumption of thin water between meals after thorough oral care, with thickened liquids still being used for meals and snacks. This protocol can help with hydration and quality of life but must only be implemented under a doctor's and SLP's strict guidance.

Conclusion: Prioritizing Safety and Quality of Life
Knowing how to thicken water for the elderly is a critical skill for caregivers addressing dysphagia. The safest method involves using commercial thickeners according to IDDSI guidelines, determined in consultation with a healthcare professional. While natural thickeners are an option, their less predictable consistency poses greater risk. A proper thickening routine, alongside careful hydration monitoring and adherence to clinical advice, ensures that seniors can remain safely hydrated while preserving their quality of life. Regular check-ins with an SLP are key to adapting the care plan as needed.
