What is Dysphagia? A Guide to IDDSI Level & Taking Care of the Patients

Swallowing is something most of us take for granted. We do it thousands of times a day without giving it a second thought. But for people with dysphagia, each swallow can be a challenge, a source of anxiety, or even a dangerous event. As caregivers, family members, or healthcare providers, understanding dysphagia is the first step toward providing proper care and support.

 

What is Dysphagia?

Dysphagia is a medical term for difficulty swallowing. It's not a disease but a symptom that something isn't working right in your swallowing process, making it hard and painful for food to pass the throat. This difficulty can range from mild discomfort to severe pain while swallowing or even the inability to swallow at all.

Many people don't realize that swallowing is an incredibly complex process involving over 50 pairs of muscles and many nerves. When you swallow, your brain coordinates a precise sequence of events that moves food or liquid from your mouth to your stomach while protecting your airway. Dysphagia occurs when any part of this process doesn't work properly.

 

Dysphagia: Common Signs and Symptoms

Living with dysphagia can be challenging and frustrating. Here are some signs that might indicate a person is struggling with swallowing:

• Pain while swallowing (odynophagia)
• Feeling like food is stuck in the throat or chest
• Frequent heartburn or chest pain
• A dry throat that makes it hard to swallow
• Coughing or choking when eating or drinking
• Regurgitation of food or liquid
• Unexplained weight loss
• Drooling or difficulty managing saliva
• Taking a long time to eat meals
• Avoiding certain foods or social eating situations

However, if you're caring for someone with these symptoms, it's crucial to consult a healthcare provider rather than attempting to diagnose the condition yourself. Only medical professionals can properly assess swallowing function and recommend appropriate treatment approaches.

 

Understanding IDDSI Level for Dysphagia Patients

The International Dysphagia Diet Standardisation Initiative (IDDSI) has developed a globally standardized way to describe food textures and drink thickness for people with dysphagia. This framework consists of 8 levels (0-7) and uses practical measurement methods that can be applied reliably across different cultures and care settings. Here’s the breakdown of these levels:

 

IDDSI Level 0

IDDSI Level 0 consists of regular thin liquids that flow easily, such as water, tea, coffee, or juice. These liquids are appropriate for people without dysphagia or those with very mild swallowing difficulties who can safely manage fast-moving fluids.

When testing Level 0 liquids, you'll notice they flow quickly through a fork's prongs, leaving virtually no residue behind. Most people without swallowing difficulties consume Level 0 liquids in their everyday diet.

 

IDDSI Level 1

Level 1 liquids are slightly thicker than water but still maintain a pourable consistency. These include thickened juices, thin smoothies, and certain syrups.

When tested, they flow through a fork's prongs but leave a thin coating on the metal. Level 1 liquids are ideal for people who find thin liquids move too quickly to control safely, giving them that crucial extra moment to prepare for swallowing.

Level 1 is particularly important for people who have mild dysphagia but still struggle with thin liquids. These slightly thickened drinks move a bit slower in the mouth, giving the person more time to control the liquid and coordinate their swallowing. This can help prevent aspiration while still being easy to drink.

IDDSI Level 2

Level 2 consists of liquids with the consistency of nectar or runny yogurt. These mildly thick liquids flow off a spoon and can still be drunk from a cup, but they move significantly slower than Level 0 or 1 liquids. Fruit nectars, thin yogurt drinks, and cream soups typically fall into this category.

People who need more time to prepare for and control swallowing benefit from Level 2 liquids, as the increased thickness provides more sensory feedback in the mouth and reduces the risk of the liquid slipping too quickly into the throat before the person is ready to swallow.

 

IDDSI Level 3

Moving up to Level 3, we find moderately thick liquids with a smooth, pourable pudding-like consistency. These liquids can be eaten with a spoon, but cannot be effectively drunk from a cup. Thick yogurt, pudding, and thick cream soups exemplify this level.

Level 3 is designed for people who need significantly more control time for swallowing and those who have moderate dysphagia. The thick consistency allows the person to form a more cohesive bolus (ball of food) in their mouth before initiating a swallow, reducing the risk of aspiration while still providing hydration and nutrition in a relatively manageable form.

 

IDDSI Level 4

Level 4 represents extremely thick, smooth foods that hold their shape on a plate and cannot be poured. These foods, such as smooth pudding, mousse, and pureed fruits without any lumps, must be eaten with a spoon.

Level 4 is appropriate for people who cannot safely manage thinner liquids or those who need more sensory input to recognize food in their mouth. The thickness of these foods means they move very slowly, giving the swallowing muscles maximum time to coordinate. Healthcare professionals often recommend Level 4 for people with moderate to severe dysphagia who can still manage spoon-fed foods.

IDDSI Level 5

Level 5 introduces soft, moist, small (4mm) pieces that require minimal chewing. These foods should be soft enough that the pieces squash easily with fork pressure. Finely minced meats with sauce and well-cooked flaked fish with sauce are good examples of Level 5 foods.

This level suits people with some chewing ability but reduced strength or coordination in their jaw and tongue muscles. Level 5 provides the sensory experience of having some texture while still being easy to form into a safe bolus for swallowing. The moisture component is crucial, as these foods should never be dry or crumbly.

IDDSI Level 6

Level 6 consists of soft, tender foods cut into bite-sized (15mm) pieces that can be mashed with fork pressure. Tender meats, well-cooked pasta, and soft fruits fall into this category. This level is ideal for people who can chew but tire easily or have reduced chewing ability due to weakness or missing teeth.

Level 6 foods provide more normal eating experiences while still accommodating dysphagia needs. The bite-sized nature of these foods reduces the risk of choking on pieces that are too large, while their softness ensures they can be broken down adequately even with limited chewing ability.

 

IDDSI Level 7

Level 7 represents normal everyday foods of various textures without modification. This level is appropriate for people without dysphagia or those with very minimal swallowing issues who can safely manage all food textures. 

Who Needs IDDSI-Certified Food?

After talking about the IDDSI levels, who actually needs these specially prepared foods? Here’s the list:

 

1. Older Adults

As we age, our muscles naturally weaken, including those involved in swallowing. Conditions common in older adults, like stroke, Parkinson's disease, and dementia, can also affect swallowing ability. According to research, about 15% of older adults experience dysphagia, with that number rising to 40-60% for those living in care facilities.

For many seniors, dysphagia can lead to malnutrition, dehydration, and social isolation if not properly managed. IDDSI-certified foods provide a safe way for older adults to continue enjoying meals while reducing choking risks.

2. People with Malnutrition

Dysphagia and malnutrition often create a vicious cycle. Difficulty swallowing can lead to reduced food intake and malnutrition, while malnutrition can further weaken the muscles involved in swallowing.

IDDSI-certified foods help break this cycle by providing nutritionally dense options in textures that the person can safely consume. This is especially important for rebuilding strength and supporting recovery.

3. Cancer Patients with Swallowing Problems

Cancer and its treatments can significantly impact swallowing function. Head and neck cancers, in particular, along with radiation therapy to these areas, can cause swallowing difficulties in up to 50-60% of patients.

Cancer-related dysphagia may be temporary or permanent, and IDDSI-certified foods can help patients maintain nutrition during treatment and recovery. For these individuals, having appropriately textured foods can make the difference between oral feeding and requiring tube feeding.

4. People Recovering from Injury or Accident

Traumatic brain injuries, spinal cord injuries, and surgeries involving the head, neck, or chest can all affect swallowing function. During recovery, these patients often progress through different IDDSI levels as their swallowing ability improves.

Having access to properly textured foods at each stage of recovery helps patients rebuild their swallowing skills safely while maintaining adequate nutrition.

Practical Tips for Dysphagia Caretakers

If you're caring for someone with dysphagia, implementing the right strategies can make mealtimes safer and more enjoyable. Here are some detailed approaches that can help.

1. Modify Food Textures Appropriately

Follow the IDDSI guidelines for food textures based on your loved one's specific assessment. Different levels of dysphagia require different food consistencies, from pureed to minced and moist.

For thickened liquids, measure thickening agents carefully using the recommended tools to achieve the correct consistency. Remember that some foods naturally change texture in the mouth, like ice cream melting, which can become dangerous for someone with dysphagia.

For a hassle-free option, CulinaCare offers perfectly textured meals that strictly adhere to all IDDSI levels, eliminating guesswork and saving you valuable preparation time.

2. Prioritize Nutrition Without Compromise

Meeting nutritional needs can be challenging with texture-modified diets. CulinaCare stands out by incorporating premium ingredients rich in essential nutrients, proteins, and healthy fats into every meal. Our dietitian-designed menu ensures proper caloric intake and nutritional balance, addressing the higher risk of malnutrition common in dysphagia patients. With CulinaCare, you never have to choose between safety, nutrition, and enjoyable meals.

3. Serve Small, Manageable Portions

Offer smaller bites that can be easily controlled in the mouth, typically about 1/2 to 1 teaspoon at a time for someone with moderate to severe dysphagia. Allow the person to fully swallow before offering the next bite, which might require counting to 10 after each swallow to ensure it's complete.

Consider serving more frequent, smaller meals throughout the day rather than three large ones if fatigue becomes an issue during mealtimes. Smaller portions on the plate also prevent the person from becoming overwhelmed or rushing through the meal.

4. Choose Foods That Hold Together

Select foods that maintain their cohesive shape in the mouth rather than crumbling or separating into liquid and solid components.

Avoid sticky foods like peanut butter or marshmallows that can adhere to the roof of the mouth, as well as dry, crumbly items like crackers, toast, or cookies that can scatter in the mouth and be difficult to control. Foods with uniform texture are generally safer than those with mixed consistencies.

5. Pay Attention to Food Temperature

Cold foods can sometimes help stimulate swallowing reflexes and increase sensory awareness in the mouth. Try offering cold applesauce, yogurt, or smoothies if appropriate for their diet level.

Ensure hot foods aren't too hot, as temperature sensation may be impaired in some people with dysphagia, increasing burn risk. Room temperature foods are often easier to manage than very hot or very cold items. The right temperature can significantly improve swallowing safety and comfort during meals.
