Understanding Allergies and Immunotherapy

Allergies are a common health concern affecting millions of people worldwide. They occur when the immune system reacts to normally harmless substances, such as pollen, pet dander, or certain foods, as if they were threats to the body. This overreaction of the immune system can lead to various symptoms, including sneezing, itching, nasal congestion, skin rashes, and even severe respiratory distress in some cases.

One of the most effective treatments for allergies is immunotherapy. Immunotherapy works by exposing the immune system to small, controlled amounts of the allergen over time. This exposure helps the immune system build tolerance to the allergen, reducing or even eliminating allergic reactions in the long term.

There are two main types of immunotherapy: subcutaneous immunotherapy (SCIT) and sublingual immunotherapy (SLIT). SCIT involves injecting small amounts of the allergen under the skin, usually in the arm, while SLIT involves placing a tablet or liquid containing the allergen under the tongue.

While immunotherapy can be highly effective in reducing allergy symptoms and improving quality of life, it is not without risks. Common side effects of immunotherapy may include redness, swelling, or itching at the injection site for SCIT, or itching and irritation in the mouth for SLIT. In rare cases, more severe reactions such as anaphylaxis can occur, which is why immunotherapy should always be administered under the supervision of a healthcare professional.

Despite these risks, many allergy sufferers find significant relief and improvement in their symptoms with immunotherapy, making it a valuable option for managing allergies and improving overall well-being.

How are Sleep Disorders Supported

The most common problem people have is falling asleep and staying asleep.  For serious sleep disorders, a doctor may advise a prescription drug to be taken nightly.

Selective Gamma-aminobutyric acid medications: These prescription medications target the GABA receptors in the brain. GABA is the neurotransmitter that reduces alertness and promotes relaxation.

Unfortunately, this medication may cause side effects like hallucinations, memory disturbances, and  “black-outs” wherein people report sleepwalking, sleep-eating, and even sleep-driving.

Benzodiazepines: Typically prescribed for anxiety, these prescription drugs activate the GABA receptors in the brain and cause sedation and relaxation. They can be considered extremely addictive with very difficult withdrawal symptoms, and can cause a similar “black-out” effect with users.

Antihistamines: These over-the-counter antihistamines are a common alternative for people who don’t want to take prescription drugs. The most common side effects of antihistamines are dryness, constipation, upset stomach, and feeling groggy the next day.

Tinnitus

Tinnitus is not a disease, and is very rarely a symptom of a serious medical problem. But it can drive people crazy. Michelangelo wrote in his memoirs that he was “plagued by the incessant chirping of crickets.” It may also sound to the sufferer like buzzing, humming or even roaring — but no-one else can hear it.

Tinnitus is surprisingly common. A British national study of hearing found that 10% of adults had prolonged spontaneous tinnitus — that is, tinnitus “usually lasting for longer than 5 minutes”; 1% had experienced severe annoyance due to tinnitus; and 0.5% had experienced a severely reduced ability to lead a normal life. Theories about the origins of this internal noise abound; treatments are scarcer. Many doctors will focus “therapy” on reassuring the patient that the problem is not life-threatening.

Hopefully this reassurance comes after a thorough medical intake and exam. With a few exceptions, surgery specifically aimed at eliminating tinnitus is obsolete. Before exploring possible treatment strategies, let us consider the two broad categories of tinnitus, and the important “rule-outs” as to the cause of this confounding auditory irritation.
