“We are led in the first instance to consider the phenomenon of dysphonia, i.e. hoarse voice or in any case the difficulty in emitting qualitatively and quantitatively valid sounds, incorrect or excessive use of the voice, viral or bacterial inflammation of the larynx, the consequences of a respiratory allergopathy or the results of gastroesophageal reflux with rising acid juices from the stomach. But there is another pathological condition, also of intestinal origin, in which among the various effects it is possible to find an important and persistent dysphonia frequently associated with marked irritation of the oropharyngeal mucous membranes. In these cases the agent responsible for the irritative phenomenology, which among other effects also causes hoarseness, is not thehydrochloric acid (Hcl), but thehydrogen sulfide (H2S) produced in the intestine following fermentation processes activated by the so-called FodMap” So the immunologist told Adnkronos Salute Mauro Minellion the occasion of World Voice Day, explains how the treatment of dysphonia also involves greater attention to nutrition.
“During the objective examination of the throat of patients with dysphonia – he underlines – significant pathologies are often not detected so, especially in cases where the patient also complains of digestive disorders such as heartburn or belching, the treatment protocol ends with the prescription of an antacid and a gastric protector, which in reality are not always effective to the point of being able to stabilize the clinical picture”.
The expert's eye focuses on the FodMap, “a heterogeneous group of carbohydrates present in a large variety of foods which, when consumed in significant quantities and assiduously by 'sensitive' subjects, can cause unpleasant disorders, not only intestinal – specifies the immunologist – FodMapactually, is an acronym composed of the initials of the words Fermentable Oligosaccharides Disaccharides Monosaccharides And Polyols. The pathological effects of the anomalous demolition of these foods by an intestinal bacterial flora altered in the fermentative sense are felt even at a distance from the point where those bacteria ordinarily reside. And, on the other hand, the low-intake diet FodMap (conceived and studied at Monash University in Australia) has proven to be able to alleviate various types of disorders, from abdominal swelling, to digestive disorders, to reflux and therefore also to dysphonia, in 75% of the cases in which it has been applied”.
“The FodMap food that most frequently causes discomfort – explains Minelli – It's lactose. And this can happen even in those people who do not have a specific intolerance. Lactose, in fact, can always be used by fermentative bacteria that may be present in excess in the intestine of subjects with dysbiosis and, consequently, generate all the disorders that are related to hyperfermentation. Difficulty in absorbing fructose is also frequent, which manifests itself with disorders following the ingestion of fresh fruit. It will be useful, in these cases, not to exceed the daily quantity of fruit, introducing at different times throughout the day a maximum of 2 portions of 150 g while avoiding apple, pear, mango, peach, apricots, cherries, watermelon. Attention should also be paid to honey and maple syrup, which contain high quantities of fructose.”
“Then there are polyols (sorbitol, mannitol, xylitol and others) – continues the immunologist – that is, sugars that are practically not absorbable in the small intestine because they are difficult to digest by our digestive enzymes. They are used in the food industry to replace part of the sugar because their sweetening power is up to 100% higher than that of sugar, even though they are low in calories. In subjects with microbial dysbiosis, they will constitute a privileged food substrate for fermentative bacteria, causing the release of volatile gas which in turn will generate a cascade of adverse effects. This is the reason why just chewing chewing gum or tasting candy can cause unexpected disorders in some individuals.”
“Since these are problems not linked to allergies, much less to misleading and fake intolerances, in all these cases the problem must be considered definitive and incurable. It will be sufficient to adequately correct the balance of a dysbiotic flora through rigorously personalized procedures and treatments and, in the in the meantime, take care of your diet by favoring foods with specific beneficial properties – suggests the immunologist – Among these foods there is certainly fish rich in omega 3 fatty acids, useful for alleviating intestinal inflammation. Also fennel, a food rich in water and low in calories which can also be taken in the form of herbal tea, it is useful in promoting correct digestion thanks to its ability to eliminate intestinal gas. Lastly, citrus fruits and pineapple rich in bromelain, an enzyme with strong anti-inflammatory power. they promote digestive processes and the absorption of intestinal gases”.
