Impact of excessive sugar on the ear and signs of hearing loss

Diabetes occurs when sugar accumulates in the bloodstream and doesn’t produce sufficient insulin. It affects around 30 million people in the country and can lead to short- and long-term complications. It’s important to learn how to manage diabetes to prevent nerve damage in various body parts, such as the hands, feet, eyes, kidneys, and ears. This article will examine how high blood sugar levels can affect the ears and the signs of hearing loss resulting from it.

Impact of high blood sugar levels on the ear
Elevated blood sugar can cause damage to the blood vessels and nerves that are responsible for hearing. This can reduce oxygen supply to the inner ear, ultimately leading to hearing loss. High blood glucose levels also impact the balance of potassium and sodium levels in the fluids in the inner ear, which can reduce cell functioning and cause tinnitus (ringing or buzzing noise in the ears that has no external source).

When diabetes affects the vestibular system in the inner ear, it may also cause balance problems and increase the risk of dizziness or falls. Diabetes can also make the earwax less acidic, making one prone to more ear canal and outer ear infections.

A study conducted by the National Institutes of Health (NIH) found that individuals with diabetes are twice as likely to have mild-to-moderate high-frequency hearing loss compared to those without diabetes. People with prediabetes also have a 30% higher risk of developing hearing loss. Some research also suggests that women with diabetes are at a higher risk of hearing loss than others. People with diabetes and high blood pressure have the lowest recovery rates from some forms of hearing loss. Early diagnosis is crucial in preventing severe damage.

Signs and symptoms of hearing loss
Some of the signs and symptoms that may indicate hearing loss are:

Trouble following conversations with more than one person
Asking others to repeat themselves
Thinking that others are mumbling
Problems following conversations in loud places like restaurants and cafes
Difficulty hearing children or people with softer voices
Turning up the volume on the TV or phone too loud
Balance and coordination issues

Exposure to loud noises like explosions, long-term exposure to music, aging, family history of hearing loss, virus, fever, ear swabs or foreign objects in the ear, structural problems in the ear, perforated eardrums, and chemotherapy can increase the risk of hearing loss for some people.

How does one protect their hearing?
While hearing loss may not be reversible, there are several ways to protect one’s hearing. Some of these include:

Get an annual hearing evaluation.
Get a moderate amount of exercise daily, as it helps improve circulation and blood flow.
Turn down the volume on personal devices such as the car radio, mobile phone, and television.
Use headphones or disposable earplugs when engaging in loud activities, such as concerts or fireworks displays.
Keep blood sugar levels as close to the target as possible.

If left untreated, hearing loss can increase the likelihood of experiencing depression, social isolation, and loneliness. Additionally, research has shown a connection between untreated hearing loss, cognitive decline, and dementia. Depending on the status of one’s auditory nerves in the ear, audiologists may recommend getting hearing aids or cochlear implants to improve hearing.

Diagnosis, stages, and prevention of heart diseases

Heart disease is a serious health condition, and it is also one of the main causes of death in the country. Irrespective of what kind of heart-related issue one has, they can be diagnosed with the help of certain tests. Once these are carried out, and a proper diagnosis is arrived at, the heart specialist, also known as a cardiologist, treats the condition accordingly. Diagnosis of heart diseases Heart-related conditions can be diagnosed via chest X-ray and blood tests. However, these are not the only available options that doctors use to determine the cause of the problems. Here is a list of some common tests that are also an option. Electrocardiogram (ECG) Holter monitoring Echocardiogram Stress test Cardiac catheterization Cardiac computerized tomography (CT) scan Cardiac magnetic resonance imaging (MRI) Different stages of heart failure Heart failure is a heart disease with different types and stages. There are mainly four stages known as A, B, C, and D. Stage A exposes one to the risk of heart failure. It can develop due to family history, hypertension, diabetes, alcohol abuse, coronary artery disease, and metabolic syndrome, among others. Stage B is more serious, as one starts to develop pre-heart failure conditions. During this stage, systolic left ventricular dysfunction occurs, which can lead to heart failure in the future.

Stages, diagnosis, and prevention of heartburn

Heartburn and GERD are often used interchangeably. However, heartburn is a common symptom experienced by people who suffer from acid reflux, and if heartburn occurs more than just twice in a week, the condition is known as gastroesophageal reflux disease (GERD). As per the National Institute of Diabetes and Digestive and Kidney Diseases, the condition affects as many as 20 percent of the country’s total population. Stages of GERD GERD is a progressive condition, and the treatment offered depends on the stage of the condition. How severely the reflux is taking place into the esophagus determines the stage of the condition. So, the various stages of GERD are: Stage I At this stage, the symptoms of the condition are mild and occur about once or twice the month. The treatment at this stage involves more lifestyle changes combined with some over-the-counter medications. Stage II When a patient is at this stage, the symptoms become more frequent and the need to take an acid-suppressive medication arises. If the medication is not taken, the symptoms of the condition can become severe and can interfere with the daily routine of the patient. When left untreated, the symptoms are also linked with inflammation of the esophagus.

Male hair loss and its various aspects

Hair grows on all parts of the human body, apart from some places like the palm of the hands and the soles of our feet. Hair is essentially made of keratin, which is a type of protein. Keratin is produced on the outer layer of the skin in hair follicles. The follicles produce new hair cells and old cells are subsequently pushed out of the surface. There are 100,000 to 150,000 strands of hair on a human head, and one loses about 100 hair in a day. Thus, hair loss can be normal. However, we should only be concerned if there is hair loss at an alarming rate. Stages of hair loss Hair loss , also known as alopecia, is divided into different types: the age at which it starts, the duration of hair loss, and the area of the body. Further there can be multiple diseases and disorders which can lead to hair loss as a side effect. There are noticeably and popularly seven different stages of hair loss. The duration of different stages can depend on the individual. The Norwood Scale defines seven stages of hair loss in men: Stage 1 Significant loss or a receding hairline is not noticed in this stage.

Hearing loss – All you need to know

Hearing loss gradually occurs as the body ages, making it common among seniors, but it can affect people of all ages due to a birth defect or damage to the ear due to an injury. Almost one-third of America’s population between the ages of 65 and 75 years suffer from some level of hearing loss. Depending on the part of the ear that’s affected, hearing loss can be divided into three types: Conductive : Hearing loss involving the outer or the middle part of the ear Sensorineural : This type of hearing loss involves the inner part of the ear Mixed : This is a combination of the other two types of hearing loss Stages Various levels of hearing loss have been identified by audiologists: Mild hearing loss People with mild hearing loss can hear sounds ranging between 25 and 40 decibels, so sounds like the ticking of a clock or a faucet dripping will be inaudible. Keeping up with a conversation that they have with one person might not be much of a challenge for people with mild hearing loss. Moderate hearing loss At this stage, people with hearing loss might not be able to hear sounds below 41 to 55 decibels.

Autoimmune diseases – All you need to know

The immune system of our body is constantly fighting against viruses and bacteria. Its job is to protect us from foreign cells that try to harm us. However, there are certain illnesses that can result in your immune system attacking your own healthy cells. These illnesses are known as autoimmune diseases. They cause the immune system to treat certain body parts as foreign elements and release auto-antibodies to attack the cells. Causes of autoimmune diseases Exactly what causes the autoimmune diseases is still unknown, but researchers around the world have come up with a few possibilities. While genetics can be at fault, your diet, certain infections, and exposure to specific chemicals may also result in autoimmune diseases. Types of autoimmune diseases There are many different types of autoimmune diseases that affect your immune system and cause it to attack the healthy cells in your body. Below is a list of the most common types. Type 1 diabetes This causes the immune system to attack the cells that produce insulin in the pancreas. Rheumatoid arthritis This illness forces the immune system to attack the joints in the body and results in stiffness, soreness, and redness. Multiple sclerosis The nerve cells in the human body are protected by a coating called the myelin sheath.
