Diet for Dysphagia - An Overview

Introduction:

The term dysphagia is a medical term that indicates difficulty in swallowing. Dysphagia can be a painful disorder. Certain situations make swallowing impossible. Dysphagia is most common in elderly persons and has an extensive number of potential reasons. Dysphagia can be brought on by any illness that impairs or affects the muscles and nerves involved in swallowing. The most common cause of dysphagia is other medical ailments, such as a brain disorder like dementia (loss of memory), stroke (interrupted blood flow to the brain), and cancers, including oesophageal (cancer in food pipe) and oral cancer.

What Are the Signs That Indicate Dysphagia?

• Discomfort when swallowing.

• Being unable to swallow.

• Having the sensation that food is lodged in one's chest, throat, or behind the breastbone.

• Drooling in anticipation.

• Hoarseness of voice.

• Food regurgitating, also known as refluxing.

• Frequent heartburn.

• Backflow of food or stomach acid into the throat.

When Is Dysphagia Diet Followed?

If having problems swallowing or chewing, there is a need to follow a soft diet intended for dysphagia. Numerous factors, including missing teeth, ill-fitting dentures, and mouth pain, could cause dysphagia. Children who are developing their teeth may also have trouble swallowing or chewing.

What Is the Purpose of a Dysphagia Diet?

Aspiration is the major risk of dysphagia. Food or liquid that inadvertently gets into the lungs is known as aspiration. In addition to other issues, it can induce pneumonia. What one eats can have an impact on how well one can swallow. Soft foods, for instance, are simpler to swallow than hard foods. Aspiration can be avoided with a dysphagia diet. These include:

• Special diets such as pureed foods or thicker liquids.

• Smaller bites.

• Alternating solids and liquids Using particular implements such as a cup, straw, or spoon.

What Are the Levels of Dysphagia Diet?

The American Dietetic Association released the National Dysphagia Diet (NDD) in 2002 to define common language and practical uses of food texture modification in the therapy of dysphagia.

It suggests categorizing foods based on eight textural attributes and designating anchor items for each attribute. The next step is to suggest a hierarchy of diet levels, with the inclusion and exclusion of foods at each level determined by a subjective comparison with these anchor foods. The NDD established four categories for semisolid/solid foods:

• NDD Level 1: Dysphagia-Pureed (extremely cohesive, homogeneous, pudding-like, needing minimal chewing ability).

• NDD Level 2: Dysphagia-Mechanically Altered (cohesive, moist, semisolid foods needing some chewing) is the second level of NDD.

• NDD Level 3: Advanced Dysphagia (soft foods that need higher chewing skills).

• Regular: Any food is acceptable.

The International Dysphagia Diet Standardization Initiative ranks foods and liquids from zero to seven on a thickness scale according to the dysphagia diet standards. Drinks are on a scale of zero to four. Foods are graded in order of thickness, from three to seven.

• 0: Thin - Flows like water.

• 1: Slightly Thick - Thicker than water.

• 2: Mildly Thick - Flows off a spoon.

• 3: Moderately Thick - Smooth texture without lumps and can be drunk from a tumbler.

• 4: Extremely Thick - Looks like a puree that can be molded as it retains its shape.

• 5: Minced and Moist - As food is moistened it can be scooped out and can be eaten using a fork and spoon.

• 6: Soft and Bite-Sized: Food can be used mashed using a fork or spoon.

• 7: Easy to Chew: Soft and tender everyday foods can be eaten.

Dysphagia Friendly Diet:

1. Food Consistency Pureed Foods: Smooth, pudding-like texture without lumps.

2. Mechanical Soft Foods: Soft and easily chewed, such as mashed potatoes, ground meats, and soft-cooked vegetables.

3. Thickened Liquids: Use commercial thickeners to achieve nectar, honey, or pudding consistency as recommended by a healthcare professional.

4. Nutrient-Dense Foods: Focus on high-protein, high-calorie options to meet nutritional needs with smaller volumes. Examples include Greek yogurt, fortified smoothies, and protein-rich soups.

5. Avoid Certain Textures:

• Hard, Crunchy Foods: Nuts, raw vegetables.

• Sticky Foods: Peanut butter, caramel.

• Mixed Textures: Soups with chunks, cereals with milk.

6. Hydration:

• Ensure fluids are thickened to the appropriate consistency.

• Use flavored water, broths, or thickened fruit juices to encourage fluid intake.

7. Small, Frequent Meals: Eating smaller, more frequent meals can help manage fatigue and ensure adequate intake.

8. Safe Eating Practices:

• Sit upright while eating and for at least 30 minutes afterward.

• Take small bites and chew thoroughly.

• Avoid distractions to focus on swallowing safely.

Which Is Better National Dysphagia Diet or International Dysphasia Diet Standardization Initiative?

The International Dysphagia Diet Standardization Initiative (IDDSI) Framework, established in 2013, is taking the place of the National Dysphagia Diet (NDD) of 2002. As of October 2021, the only diet framework that is officially recognized and endorsed is IDDSI. On experimenting different thickened drinks had different thickener concentration ranges for the classification of NDD levels when compared to IDDSI levels, and the kind of drink had an impact on these differences. Furthermore, for IDDSI classification utilizing IDDSI flow tests (SFT or FDT) in clinical practice, knowledge of the variations in thickener concentration for categorizing thickness levels between the NDD and IDDSI appears important. Based on the IDDSI flow tests, the study's results may be helpful in forecasting the viscosity or thickness of thickened drinks. They may also point to the need for better experimental guidelines regarding the IDDSI-level settings of thickened drinks.

What Are the Outcomes of Following Dysphagia Diet?

• To lower the danger and increase knowledge of choking, dehydration, undernourishment, and aspiration.

• To increase knowledge of the significance of diet and hydration.

• The target population will be aware of the risks associated with aspiration, choking, and malnourishment as well as their challenges with eating, drinking, and swallowing.

• The target group will be aware that certain foods and liquids are advised for them.

• The intended audience will know how to prepare meals and liquids.

• The target population will be prepared to follow nutritional and hydration recommendations safely.

Conclusion:

Individualized diets for dysphagia are designed to address each person's unique dietary requirements, promoting better health, symptom management, and recuperation from diseases or injuries. Therapeutic diets are an integral part of medical care and are frequently used in conjunction with other therapies and drugs.
