What causes hearing loss? + How to ensure you can help it as you age

The partial or total inability to hear is known as hearing impairment or hearing loss. It can be present at birth, or develop later in life.

There are a number of factors, which may cause hearing loss

1. Age - Age is the biggest factor when it comes to the loss of hearing, and you may lose the ability to hear as you age. This condition is known as presbycusis. It becomes difficult to understand high-frequency sounds like that of a child or a woman when you get old.

2. Noise - When you are exposed to loud noises for a prolonged period of time, it damages your ears. This leads to loss of hearing. 5% of the total population of the world is affected by noise (the degree of suffering varies). It may be a result of continuous exposure to loud music or a sudden exposure to a loud noise like an explosion.

3. Hereditary disorders - Hearing disorder may be inherited by the dominant or recessive genes of parents in the child. 70-80% of these cases inherit from the recessive genes, whereas 20-25% inherit hearing loss from the dominant genes.

4. Trauma - Serious injuries of the head/ears may cause loss of hearing, which may be either temporary or permanent. When damage is caused to the brain, the brain fails to process the message conveyed by the ears. So even if the ears are totally functional, a person may face the problem in hearing.

5. Perinatal problems - The ototoxic effects on the fetus due to excess intake of alcohol during pregnancy lead to hearing the loss in about 64% of the infants born to alcoholic mothers.

Also, premature birth can be associated with hearing loss due to high risk of being exposed to noise in neonatal units.

Knowing about the causes of hearing loss can lead you a step closer to preventing this disorder as you age.

Here are some useful tips that can help prevent hearing loss:

1. Be more aware - You should be diligent and aware of the situations, which may risk your hearing ability and should try to avoid such situations as much as possible. Limit your exposure to sources of hazardous noises like firearms, firecrackers, concerts and clubs.

2. Take precautionary measures - If your occupation calls for working at an environment of loud noises, use earplugs or earmuffs to block out the excessive noise. Also, make sure that you work in a place where employers take all the necessary measures of noise control under the federal or state regulations.

3. Monitor your use of gadgets - Monitor and control the use of hearing devices, and try to reduce the use of headphones/ earphones as much as possible.

Growth is the most important aspect of childhood, one that distinguishes children from adults. Growth is affected by a number of diseases and growth failure is often the first sign of a serious disease. Unfortunately children with growth failure present very late when no help is possible. 

Why to worry?

Growth is the best marker of health and growth failure may be caused by a seious disease. Moreover children with short stature have lower self esteem. 

When to worry? 

Plot the height of your child in the growth chart and if it is below the lower limit visit a doctor. Alternatively if your child's height is less than the formula (Height = Age in years x 6 + 77 cm) it may be a cause of concern. Growth stops at the age of 14 years in girls and 16 years in boys. Hence the child should be reviewed latest by 10 years for girls and 12 years for boys. 

What causes growth failure? 

Growth failure can be due to a number of causes including poor nutrition, lack of physical activities and low genetic potential with parents being short. Short stature can also be caused by a number of diseases like thyroid problems, growth hormone deifiency and celiac disease (wheat allergy). 

How can I improve my child's growth?

Please encourage your child to play for atleast 1 hour a day. It is important to restrict screen time including television, computer, tablets and mobiles to less than an hour. Increased protein and calcium intake with more milk, pulses and vegetables also helps in improving growth. Growth hormone is produced during sleep. Sleeping for at least eight hours a day is therefore essential for a child to achieve good growth. 

What can be done if my child is very short? 

Please consut a doctor to identify the cause of short stature. Most conditions are readily treatable. Children with growth hormone deficiency respond dramatically to growth hormone. Growth hormone is also being used now in children with turner syndrome, familial short staure, small size at birth and kidney disease. 

Time is important- act now if your child is short. 

Is My Child Short? 

Is your child refusing to grab anything other than chicken nuggets? When your child s nutrition is an aching subject to deal with in your household, remember you are not the only one. Many parents are actually worried about the fussiness of their children over food. But your child s food preferences would also mature with age. Until then, you can consider trying out these following tips to avoid any kind of mealtime hassles.


Respect your child's appetite or lack of one: Respect your child s level of appetite and never force a meal, if your child is not hungry. Rather, serve small portions to give them an opportunity to ask for more, on their own.
Stick to the routine: Maintain a routine and serve snacks and meals at about the same time every day. Also, keep a check on the number of times you serve those mid meal snacks and try to stick to that count.
Be patient with new foods: Have patience with new food. Take time in introducing it to your child by talking about the food s shape, color, aroma and texture, if not the taste.
Make it fun: Try out innovative ways of garnishing your food so as to make the whole eating experience a fun and a thrilling one for your child.
Recruit your child's help: At the grocery store, ask your child to help you select vegetables, fruits and other healthy foods. But keep off those foods which you would not want you child to eat.
Set an example: Set an example by yourself by eating all kinds of nutritious and healthy foods, in order to set that perfect example for your child.
Cut Distractions: Make sure to switch off from any sort of a distraction, such as the television or the washing machine and other electronic gadgets while feeding your child.
Don't offer dessert as a reward: Do not reward your child with desserts at the end of the meal as this sends them an indication that the dessert is the best dish among all.
Do not cook a separate meal: Do not cook a separate meal for your child after he/she has refused the original one as this might encourage picky eating even more.

How To Deal With Picky Eaters (Children)?

The term pollution means introduction of harmful and unwanted contaminants into our environment. Due to the borderless nature of our atmosphere and oceans, contamination at a small level can have a huge impact that to in places which are nearby and one of the best examples of this is crop stubble burning in Punjab and Haryana which is a major contributor to Delhi smog. Pollution is a slow poison and is deleterious to the life of all beings, including plants, animals, and humans. With the rise in the pollution levels, no one can escape the harmful effects of the same on health. Though pollution poses a great threat to everyone, it is the children who are most effected, let us read on to know the reasons

Why are children more susceptible to pollution?

The lung function, immune system, and metabolic systems in children are not fully developed and functional which makes it difficult for the body to fight these pollutants.
Children breathe in more air per kilogram of their body weight than adults, so they take in more pollutants per breath.
Children are not only more active but also have a faster breathing rate than that of adults. This means that they take in more environmental toxins and at a much faster rate.
What are effects of pollution on children s health?

Exposure of pregnant women to polluted air is strongly associated with premature birth, low birth weight, and intrauterine growth retardation. Low birth weight babies and premature infants are more prone to developmental delays and other disorders.
Exposure to certain pollutants like carbon monoxide and ozone are linked with septal and valvular defects in the heart of a child.
There is a strong association between particulate pollution and symptoms like wheezing and bronchitis in both adults and children. This is the main reason why there is an increased prevalence of Asthma in children in urban areas. Research has shown that high level of pollutants in air cause deficits in lung function growth.
The immune system which protects the body from infections and germs is not fully developed in children. Pollutants are known to cause suppression of immunity in small children making them more prone to infections.
Children need sufficient Vitamin D for strong and healthy bones. Vitamin D is known as sunshine vitamin and is synthesized in the body on exposure to UVB rays of the sun. Increased particulate components in the air reduce the amount of UVB radiation reaching the ground level. More than 60% children are Vitamin D deficient and require supplements orally.
The exhaust of gasoline and diesel is known to emit carcinogens which are thought to play a role in the development of leukemia (blood cancer) in children.
The nervous system is a target for many environmental pollutants. Exposure to these pollutants can lead to neurological deficits and delays in development. Some of these effects are irreversible and long-lasting.
Unfortunately, with urbanization and increased population, the levels of particulate pollutants in the air are increasing at an alarming rate. The problem of pollution needs to be addressed immediately, until then it is best to keep the children indoor and take necessary precautions and keep children safe from exposure to the pollutants.

Pollution - How Is It Worse For Children?

The most advanced and effective communication device in this century is mobile phone. Mobile phone is not only being used by the corporate or highly qualified professional. People from all type of social group have mobile phone in their hands now. Usage of the mobile phone is not increased only with all social groups but also with people of all age groups. Children are the more noticeable group as they are using cell phones of all types. A recent research study shows that children are really capable of using any advanced type of mobile phones even without any proper guidance. Though mobile phones are the effective mode of communication, it is a well known fact that it also has adverse side effects if being over used. The mobile phones emit shockwave radioactive radiations that affect the body in various manners.

Adverse effects of mobile phone usage:

Today's children are growing up in a radio-frequency environment that never existed in human history before. The radiation emitted by mobile phones and mobile phone masts can have adverse effects on children. Some include:

Affects your Immunity Status: cell phones after a full day usage contains many germs on their display which are highly numbered than your toilet seats. These germs are easily transferred to your body as you touch frequently or use close to your face for talking. This increases the risk of exposure to the germs and reduces your immune strength as immune status are not fully developed for children.

Increase Risk of Chronic Pains: prolonged use of mobile phones for playing games or texting requires continuous movement for your hands which may develop chronic pain in joints of your hands and shoulders.

Vision Problem: children when concentrate much on playing games in mobile phone they even fail to blink frequently with the increased interest and attraction towards the game. This causes the dryness of the conjunctiva and also increases the ocular tension.

Affects your emotions negatively and increases the stress level

Mobile Phone Safety For Kids:

As a parent, you must take preventive measures to minimize your child's exposure to the harmful effects of mobile phones. These include:

Do not give cell phone if your child is under 16 years. A child's brain is too sensitive to withstand the effects of mobile radiation.

Do not let your child hold a mobile phone directly up to his head. Use an air-tube headset instead.

Do not let your child make calls in buses, trains, cars, and elevators. The mobile phone works harder to get the signal out through the metal, which increases the power level.

Do not let your child use cell phone when the signal is weak. It will increase the power to the maximum, as the phone attempts to connect to a new relay antenna.

Limit the use of cell phone around children.

Make sure that there is no mobile phone mast or network tower near your home or your kid's school.

Do not let children take mobile phones to school.

Do not leave mobile phones in your children's bedroom at night.

Effect of Excessive Use of Mobile Phones on Children Health

Cochlear Implant is an electronic device replaced with the inner ear (cochlea) of the patients who are unable to send sound waves to the brain.

The surgery is performed on the patients who have the problem of hearing loss due to the damaged hair cells in the inner ears. The implant helps the patient to hear which are not responding to other hearing aids.

Conditions for Cochlear Implant:

Cochlear implants help people to hear with clarity. They are not like hearing aids, which make the sound louder, but it helps send sound waves to the brain and replaces the damaged hair cells in the inner ear. Following are cases where it is beneficial:

People who find it difficult to hear clearly with hearing aids.

Those with moderate hearing loss in both ears.

Patients with 50% or fewer score in the sentence recognition test.

Patients with 60% or less score in sentence recognition test with hearing aids on.

It is suggested to opt for cochlear implants in both ears. The reason is to give the patient a better perspective of sound direction and clarity in understanding the words.

How does the Cochlear Implant work?

Cochlear Implant is an electronic device with an embedded sound processor that has to be worn outside ears or on the body. Following steps are involved in cochlear implant:

The sound captured by the processor is converted digitally by the processor and sent to the coil inside the ears of the patient.

The implant converts digitally coded sound waves to electrical impulses.

The electric impulse simulates the hearing nerve of the patient.

Then sends these impulses to the brain.

Benefits of Cochlear Implants:

The cochlear implant is a blessing for people who have been suffering from hearing loss for a very long time. It provides aid to people who have not benefited from hearing devices. The benefits of the cochlear implant are:

Hear better.

Studies have shown that people with cochlear implants have better sentence recognition scores instead of hearing aids.

The patient can concentrate better in the crowd and can hear conversations across the table.

Reconnect with the missed sounds.

Enjoy music on the phone.

Cochlear Implant improves the quality of life of people with hearing loss. It gives them an aid to understand and engage themselves in a conversation. However, it takes time to learn the interpretation of the sound signals that are received from cochlear implants. But, the patient can learn and lead a normal life with the implant. The factors which affect the benefits of Cochlear implants are:

The extent of hearing loss

The duration of the hearing loss and the condition before implantation

Damage to inner hair cells

Other health issues

The practice and rehabilitation time have been done in practice after implantation

The cochlear implant is performed in the patients after taking extensive tests determining the condition of the patients. It is activated after 2-6 weeks of surgery to give the surgery site a time to heal. Most people are discharged from the hospital after surgery and are prepared for the use of an implant. There are training sessions and classes for patients who have just gone for cochlear implants.
