Do you or somebody you know have difficulty swallowing, chewing your food, or both? If you have experienced a stroke, head or neck injury, cancer, cerebral palsy, or dementia this could be a side effect of your condition. Difficulty with chewing and swallowing can also be due to the average aging of a person.
Difficulty swallowing and chewing of the food is clinically named dysphagia. Dysphagia should be evaluated and treated by a multidisciplinary team consisting of a radiologist, a speech pathologist or occupational therapist, a dietitian, and a nurse. When swallowing difficulties arise there may be a number of problems occurring. There are four types of swallowing difficulties; esophageal phase dysphagia, oral preparatory dysphagia, oral dysphagia, and pharyngeal phase dysphagia. Oral dysphagia is defined as presenting a difficulty controlling the food bolus while in the mouth. Oral preparatory dysphagia is defined as difficulty taking food, chewing, mixing with saliva, and creating a food bolus. Esophageal phase dysphagia is a difficulty with the food bolus when it reaches the esophagus. There may be a delay in action due to the person’s condition. Pharyngeal phase dysphagia defined is difficulty swallowing food due to it becoming trapped at the top of the pharynx of the throat. Aspiration, or the inhaling of food particles into the lungs, is a result of inadequate chewing and/or swallowing. It is said to be a major contributor to respiratory infections and pneumonia in adults that are institutionalized. This poses a large problem to the brain injury community as a whole.
If the person has a large difficulty swallowing, they may be on a non oral feeding method for the majority of their nutrients. There are three ways the person may experience a tube feeding. Mostly used for a short time to deliver nutrients to a person is the Nasogastric Tube, or NG. This is a long tube that passes through the nasal cavity and down to the stomach. Liquid nutrients are then given either several times daily or throughout the night while sleeping. As you can imagine, this is not very comfortable, which is why it is used only for short term. The second method is a Percutaneous Endoscopic Gastrostomy or PEG tube. This is used for long term delivery of nutrients directly into the stomach. Nutrients are given in the same manner as a NG tube would be. The only difference is that a PEG tube is surgically placed through the abdominal wall, directly into the stomach. The last way to receive nutrients into the body for a non oral feeding person would be through an IV. An intravenous catheter is placed directly into a vein and nutrients are pushed through the blood.
After a person has experienced a life altering event that leaves them with a brain injury, they often find themselves with some sort of non oral feeding method in place. They must then work their way back to a regular diet of eating normally. But first they must go through many scans to see if the body is working properly to transport the food bolus from the mouth to the stomach. If difficulty arises in chewing of the food and transporting it to the back of the throat a puree diet may be put in place. A puree diet is designed for patients presenting a difficulty chewing and swallowing food. All foods should be blended until smooth, and may need to be thickened with a gelatin based food thickener. Thickeners may be useful for adapting pureed foods to meet individual needs. When food is pureed a spoon should be able to stand up in the center without falling to the side of the bowl or cup it is served in. The person is allowed some foods and should avoid the following. Breads and crackers are typically not permitted while a person is on this diet. Nuts, dried fruit, seeds, and desserts that crumble should be avoided. Raw, tough, or vegetables with skins will not easily blend and should be avoided. Tough meats, cheese, and peanut butter pose a difficulty while blending and should be avoided as well while on a puree diet. Some foods that are allowed while on this diet consist of pudding, yogurt without fruit pieces, applesauce, and blended canned fruit. You may need to thicken the applesauce and canned fruit after blending. Well cooked vegetables without skin or seeds are allowed but may need to be blended and thickened to pureed consistency. All meats must be blended until smooth. Fish, poultry, and ground meat may be tender enough to puree well. Gravy can be used to maintain a smooth consistency while blending meat. These were examples of foods that may or may not be consumed while on a pureed diet.
The next step up in dietary restrictions would be a mechanical soft diet. This diet is designed for individuals who have difficulty chewing food but are able to tolerate a wide variety of foods. It includes foods that are soft in texture, semi-solid, moist, and can stick together. Foods must be presented to the person in bite size amounts. A mechanical soft diet gives the person some chewing ability while eating. While on this diet bread is avoided along with dry, hard, crumbly, crispy, or sticky foods. Some foods that are allowed are sugar and sugar substitutes, bite sized, chopped canned fruit, bananas and juices. Watermelon should be avoided if the person on this diet also restricted by thickened liquids. Foods that should be avoided are jams, preserves, all candies, and any items with seeds, nuts, dried fruits, hard/dry toast, and French toast. You may change the consistency and texture of foods to fit this diet by cooking, chopping, mincing, or mashing them.
There’s another step on the dietary restriction list. It is the edentulous soft diet. This diet is very particular as to what may be consumed by the individual. There is some debate surrounding this diet due to it being so similar to a mechanical soft diet. The only difference in the two would be the foods allowed and avoided. If you have been placed on this diet please ask your team of specialists for a list of foods you are allowed to have.
After you have made the progress necessary you may be able to eat a regular diet without any restrictions. These foods would be prepared normally without any mechanical alterations necessary. But you may not be able to consume regular thin liquids.
Often times when a person is diagnosed with Dysphagia they have problems with consuming thin liquids. These drinks must then be altered by a thickening agent to be consumed by the individual. Thin liquids may be thickened to nectar, honey, or pudding consistencies depending on the needs of the person. Nectar thick liquids are a bit thicker than thin liquids, much like a glass of eggnog, tomato juice, or peach nectar would look. Honey consistency liquids are easily offered on a spoon to the individual. They may be controlled in the mouth easier than thin or nectar thick liquids. There are no natural liquids this consistency without a thickening agent. Pudding thick liquids are used when a person has little to no control over their tongue and mouth movements. These liquids should be given by a spoon to the individual; each bite should be no more than a half of teaspoon of the liquid. It should be kept in mind that there are many things that have “hidden” liquids. These items would be jello, ice cream, watermelon, and any other substances that possibly melt from a solid to a liquid. There are many ways to thicken thin liquids, utilizing bread crumbs, instant apple or potato flakes, instant baby cereal, instant flour, and instant pudding mix. Commercial agents such as Thixx, ThickenUp, and Thick It, may also be used to thicken up foods and liquids.
If you or somebody you know is having difficulty swallowing or chewing food, I hope this article gave you some insight as to what could be happening. If you have any questions please see your doctor or speech pathologist to confirm or deny any type of dysphagia. I wish you the best of luck in the future with any difficulties swallowing or chewing food or drinking liquids.
