What is Tinnitus?
Tinnitus is a condition characterized by the perception of sound without any external stimulus. The sound may be described as ringing, buzzing, hissing, or humming and can be heard in one or both ears. Tinnitus can be categorized into two types: subjective and objective. Subjective tinnitus is the most common type and is only heard by the individual experiencing it. On the other hand, objective tinnitus can be heard by a healthcare professional during an examination.
A variety of factors, including noise exposure, age-related hearing changes, head or neck injuries, ear infections, and certain medications, may contribute to tinnitus. The mechanisms underlying tinnitus are not fully understood, but it is thought to involve changes in the brain's auditory system, including the neural pathways that process sound.
There is currently no cure for tinnitus, but there are approaches available that can help manage symptoms. Cognitive-behavioral therapy, sound therapy, and tinnitus retraining therapy are all options that have been shown to be effective in reducing the impact of tinnitus on an individual's quality of life. In some cases, medications such as antidepressants or anticonvulsants may also be used to help alleviate symptoms.
One of the biggest challenges in managing tinnitus is its subjective nature, making it difficult to measure and evaluate the effectiveness of different approaches. However, tinnitus research is ongoing, and new therapies are being developed that target the underlying mechanisms of the condition.
Tinnitus Symptoms
Tinnitus is the perception of sound in the absence of an external source and can be experienced in a variety of ways. The most common symptom of tinnitus is the perception of a continuous or intermittent ringing, buzzing, or hissing sound in one or both ears. However, tinnitus can also present as a pulsing or thumping sensation or as a low-frequency rumble.
Tinnitus can vary in severity and duration and can be experienced differently by each individual. Some people may only experience mild symptoms that are tolerable, while others may find their symptoms challenging and distressing. In some cases, tinnitus can also be a sign of an underlying health condition, such as hearing changes, ear infection, or head and neck injuries.
Other symptoms that may accompany tinnitus include difficulty sleeping, difficulty concentrating, irritability, anxiety, and feelings of sadness. These symptoms can significantly impact an individual's quality of life and may require professional support.
What Causes Tinnitus?
While tinnitus is commonly associated with hearing changes, it can also be related to a variety of other factors.
One common factor contributing to tinnitus is exposure to loud noise. This can affect the sensitive hair cells in the inner ear that are responsible for transmitting sound signals to the brain. Over time, this exposure can result in tinnitus. Individuals who work in noisy environments, such as construction sites or music venues, may be particularly at risk.
Another factor contributing to tinnitus is age-related hearing changes. As individuals age, their hearing can gradually change, resulting in tinnitus. Additionally, certain medications, such as aspirin, ibuprofen, and some antibiotics, can contribute to tinnitus as a side effect. This type of tinnitus is typically reversible once the medication is discontinued.
Other health conditions contributing to tinnitus include ear or sinus infections, high blood pressure, diabetes, thyroid disorders, Lyme disease, and Fibromyalgia. Tinnitus can also be a sign of Ménière's disease, a disorder of the inner ear that affects balance and hearing.
In some cases, tinnitus may be related to underlying psychological factors, such as stress or anxiety. This type of tinnitus is often managed with a combination of cognitive-behavioral therapy and sound therapy. In severe cases that require immediate medical attention, tinnitus may be related to acoustic tumors or traumatic brain injuries.
While tinnitus can be distressing, it is a manageable condition in many cases. Options to explore may include hearing aids, white noise machines, and tinnitus retraining therapy. It is important to see a healthcare professional if you are experiencing tinnitus, as they can help determine contributing factors and develop a plan that is appropriate for you.
Functional Medicine Labs to Test for Factors Contributing to Tinnitus
In order to assess tinnitus, a healthcare professional will typically perform a thorough physical examination, including a hearing test and other diagnostic tests, such as a CT or MRI scan. This section will examine functional medicine labs that can help assess contributing factors to tinnitus.
Allergy Profile
Chronic respiratory allergies can lead to chronic sinus infections, which are a possible factor contributing to tinnitus. The Inhalent Allergen Panel will assess for 46 of the most common inhalant allergies, which can be a beneficial test if chronic allergies are suspected as a contributing factor to tinnitus.
Comprehensive Metabolic Panel (CMP)
The CMP test provides information about your body's chemistry and metabolism. Abnormal results can indicate health conditions such as diabetes or hypertension which are both possible factors contributing to tinnitus.
Full Thyroid Panel
Since thyroid disorders can contribute to tinnitus, a full thyroid panel is recommended to assess for underlying thyroid dysfunction or disorders if this condition is suspected to be a contributing factor to tinnitus.
Tickborne - Lyme & Tickborne Relapsing Fever (TBRF)
While the standard test to assess Lyme Disease is an Elisa test and Western blot, the Tickborne - Lyme & TBRF comprehensive functional test to detect Lyme Disease can be helpful in assessing tinnitus related to Lyme Disease symptoms.
GI360 Microbiome
Disturbances in the gut microbiome (dysbiosis) have been shown to play a role in chronic pain conditions such as fibromyalgia. The GI360 test is a DNA analysis that identifies and characterizes the abundance and diversity of more than 45 targeted analytes that have been shown to contribute to dysbiosis, which can lead to fibromyalgia. This test can be beneficial in assessing tinnitus related to fibromyalgia.
It's important to note that testing for tinnitus may vary depending on the severity and duration of the symptoms, as well as the underlying factors. A comprehensive evaluation by a healthcare professional is essential to properly assess and manage tinnitus. Healthcare professionals can also develop a plan that is appropriate for the individual utilizing the lab tests mentioned in this section.
Supplements & Herbs for Tinnitus
While supplements and herbs may have the potential to support the management of tinnitus symptoms, they should not be used as a substitute for medical treatment. Speaking with a healthcare professional before starting any new supplement or herb regimen is always recommended, as some may interact with other medications or have side effects.
One commonly studied supplement is melatonin. Melatonin is a hormone that helps regulate the body's sleep-wake cycle and has been found to have antioxidant properties. Some studies have suggested that melatonin at 1 mg to 3 mg per day may help support the management of tinnitus symptoms, particularly in individuals who also have sleep disturbances due to its antioxidant qualities.
Another supplement that has been studied for its potential to support tinnitus management is zinc. Zinc is an essential mineral involved in various bodily functions, including the immune system and wound healing. Some studies have found that zinc supplementation at 50 mg per day may help support the management of tinnitus.
Ginkgo biloba is an herb that is commonly used for its potential cognitive benefits. While research on ginkgo biloba for tinnitus has been mixed, some studies have suggested that it may help support the management of symptoms in individuals with mild-to-moderate tinnitus.
Magnesium is another mineral that is important for hearing health. It plays a role in regulating the flow of potassium ions in the inner ear, which helps maintain normal hearing function. A systematic review completed by the Mayo Clinic found that magnesium supplementation may help support the management of tinnitus. The recommended dose of magnesium for tinnitus in this study was 532 mg per day. Magnesium can be taken as a supplement or obtained through dietary sources such as almonds, spinach, and black beans.
Other herbs should also be considered and individualized depending on the results from the above functional labs. If allergies are a contributing factor to your tinnitus, Butterbur is a herb that has been shown to support allergy management. Polyphenols are powerful plant compounds that are useful for managing metabolic syndrome and associated conditions like diabetes and hypertension. For thyroid disorders, ashwagandha is an herb that can be used to support balanced TSH and thyroid hormone levels. Lyme disease is difficult to manage. However, if Lyme is a contributing factor to tinnitus, Uncaria tomentosa (Cat's Claw) and Scutellaria baicalensis (Chinese Skullcap) are herbs that may be helpful. Ginger is an excellent anti-inflammatory herb that may be helpful in the case of dysbiosis.
In addition to these supplements and herbs, other natural approaches such as acupuncture, hypnosis, and biofeedback have also been studied for their potential to support the management of tinnitus symptoms. While some studies have found these therapies to be helpful, more research is needed to determine their effectiveness in managing tinnitus.
It's important to note that these dosages are general suggestions and may not be appropriate for everyone. Additionally, choosing high-quality supplements from reputable manufacturers is important to ensure safety and effectiveness.
