Night blindness is also called nyctalopia.It's a type of vision impairment. People with night blindness experience poor vision at night or in dimly lit environments. It is not a disease in itself, but rather a symptom of an underlying problem, usually a retina problem.

What Causes Night Blindness?
A number of eye conditions can cause night blindness, including:
1. Nearsightedness or blurred vision when looking at faraway objects.
2. Cataracts or clouding of the eye's lens.
3. Retinitis pigmentosa, which occurs when dark pigment collects in your retina and creates tunnel vision.
4. Vitamin A Deficiency
5. Zinc Deficiency
6. Dry Eyes
7. Diabetes

Are the Symptoms of Night Blindness?
The sole symptom of night blindness is difficulty seeing in the dark. You're more likely to experience night blindness when your eyes transition from a bright environment to an area of low light, such as when you leave a sunny sidewalk to enter a dimly lit restaurant. You're likely to experience poor vision when driving due to the intermittent brightness of headlights and streetlights on the road.

How can I Prevent Night Blindness?
You can't prevent night blindness that's the result of birth defects or genetic conditions, such as Usher syndrome. You can, however, properly monitor your blood sugar level and eat a balanced diet to make night blindness less likely. 

Orange colored foods are excellent sources of vitamin A, including:
1. Cantaloupes
2. Sweet potatoes
3. Carrots
4. Pumpkins
5. Butternut squash
6. Mangoes

What are the Treatment Options for Night Blindness?
The treatment will depend on its causes.
1. Nutrient deficiency (Vitamin A and Zinc) is the easiest to treat. 
2. If the cause is cataract, you can go for cataract surgery to remove the clouded lens and replace it with artificial intraocular lens. Vision is usually dramatically improved after surgery. 
3. For dry eye syndrome, lubricate your eyes with artificial tear drops as they provide instant relief. Just make sure that they are without preservatives. 
4. Diabetic retinopathy can be prevented with tight control over blood sugar, active lifestyle and good dietary habits.
5. As for retinitis pigmentosa, unfortunately there are no treatments available. Thankfully, new research is showing that vitamin A might have a slowing effect on the progression of this eye disease.

Night Blindness: Causes and Symptoms

A head louse is an insect that lives on the human scalp and feeds on human blood. The female louse lays eggs in the head and makes sure the eggs are attached to the hair shaft. It takes around eight days for the egg to hatch. The louse takes another 11 days to mature into an adult louse.

Causes:
The primary cause of head louse is poor personal hygiene. Other causes due to which a person can be infected by lice are:
1. Using combs and towels that are infested.
2. Coming in contact with another person who has this condition.
3. Sharing the bed with a person who is affected by lice.

Symptoms:
When a person is affected by this condition then the following symptoms are observed:
1. The saliva of the lice causes an allergic reaction in the scalp which leads to constant itching. It can occur in various places such as ears, scalp and the neck. It may not occur initially, but it tends to occur after a few weeks.
2. Constant scratching can lead to formation of small red bumps on the skin. A bacterial infection usually occurs from constant itching.
3. It may lead to symptoms of dandruff in the scalp.
4. Presence of various insects in the scalp.

Prevention of Lice:
Lice can be prevented by using medicated shampoos and conditioners to wash the hair. The shampoos are usually based on a chemical called pyrethrin. This compound is toxic for lice and helps in getting rid of it.

You can also opt for the following lifestyle changes to prevent lice:
1. You should avoid sharing your hairbrush with others.
2. In case you have long hair, tie it in buns or ponytails.
3. Add tea tree oil to your shampoo before using it.
4. Keep the scalp clean to prevent infestations.
5. Avoid sharing pillows and clothes.

Causes, Symptoms and Prevention of Lice

Irritable bowel syndrome (IBS) or spastic colon is a rather common intestinal tract disease which is characterized by sharp pain in the stomach, stomach gas, diarrhea or constipation. It is a chronic condition whose exact cause, although unknown, is sometimes attributed to the dysfunctional production of the neurotransmitter, dopamine.

There is no particular treatment for IBS. However, the symptoms can be brought under control through various methods. The symptoms of IBS can be controlled by making lifestyle changes such as incorporating certain modifications to your diet and reducing or managing stress levels. For severe symptoms, you may require medications.

Patients may also consider homeopathic treatment for a rather wholesome effect and lesser side effects. The purpose of homeopathic treatment is to stimulate the body s inner self-balancing mechanisms. In order to achieve this, this person must be provided with the right solution at the right time. Since homeopathy aims at treating the root cause of the problem, the treatment is stretched over a longer period of time. Additionally, homeopathy functions by stimulating the natural healing capabilities of the body. Some of the common homeopathic medications that can be used to treat IBS are listed below:

Pulsatilla: Prepared from a medicinal plant known as wind flower, Pulsatilla is effective in the cure of IBS with its remedying effect on the gastrointestinal tract.
Nux Vomica: This too is derived from a plant and has a positive effect on the digestive and nervous system, thereby being effective in the treatment of IBS.
Sulphur: It is one of the most common choices among homeopathic practitioners for IBS. Sulphur affects the digestive tract and is helpful in the treatment of intestinal gas and constipation. It is usually prescribed for individuals who are rather thin and physically weak.
Lycopodium Clavatum: This is mainly prescribed for people with diarrhea and stomach gas. This drug acts specifically on the gastrointestinal tract
Asafoetida: This drug is prescribed when there is a fairly common constriction in the bowel muscles.

Irritable Bowel Syndrome - 5 Homeopathic Remedies For It

Also called gluten-sensitive enteropathy and celiac sprue, celiac disease is an autoimmune digestive disorder, wherein the consumption of gluten-based foods leads to damage of the tissues that line the small intestine. This hinders the ability of your body to absorb the essential nutrients from the foods you eat.

Causes
Under normal conditions, the immune system of the body offers protection against external intruders. When individuals diagnosed with celiac disease consume gluten-based foods, gluten resistant antibodies are formed by the immune system. This causes them to attack the linings around the intestines, thus causing irritation in the digestive tract and harming the villi (hair-like structures on the covering of the small intestine which absorb nutrients from the food). This impairs the nutrient absorbing capacity of the individual, thus increasing chances of malnourishment.

Symptoms
Celiac disease has symptoms that vary from patient to patient. Some of the common symptoms include:

A severe skin rash called dermatitis herpetiformis.
Digestive problems such as:
Pain
Gas
Abdominal Bloating
Diarrhoea
Weight loss
Pale stools
Musculoskeletal problems such as bone and joint pain as well as muscle cramps
Seizures
Aphthous ulcers which are basically sores occurring in the mouth
Tingling sensation in the legs which are caused by low calcium and nerve damage
Growth issues in children since they cannot absorb the required amount of nutrients
Irregular menstrual cycles
Other complications associated with celiac disease

Miscarriage or Infertility
Osteoporosis. This is a disease which weakens the bones and causes fractures. It is caused because of a deficiency of Vitamin D and calcium.
Intestinal Cancer
Other birth defects: Such as irregular spinal shape because of the deficiency of certain nutrients, especially folic acid.

Celiac Disease - Signs You Are Suffering From It!

Fractures are simply a break in a bone. They can be caused due to injury, (traumatic fractures) or a pre-existing condition like osteoporosis that causes weakening of bones (pathologic fractures). There are many ways to classify fractures. All fractures fall into the major categories of simple and compound fractures. Simple fractures are fractures where bones remain inside the skin and don t jut out. They are also called closed fractures.

Compound fractures, also called open fractures, are broken bones that penetrate through the skin. These types expose the bone and deep tissues to the environment. Compound fractures are more serious of the two. The healing here may be affected due to deep infections for which antibiotics need to be used. There are many different sub types of fractures and we re only going to skim through them here.

Comminuted fractures: Severe fractures in which a bone breaks into several smaller pieces.
Avulsion fractures: A small piece of bone is completely torn off from the main bone due to fierce pulling off a part of the body.
Other types of fractures are characterised by the many different angles the bone breaks into like transverse, oblique and spiral fractures.

Diagnosis
When a bone is broken there are symptoms like swelling that doesn t subside on its own and pain. In such a case it s imperative that one goes to a doctor for a diagnosis. Doctors can usually recognise most fractures by examining the injury and taking an X-ray. The X-ray also provides a clear idea about the type of fracture and the degree of displacement of the bone. And, it s important that the patient doesn t wait too long before approaching a doctor. This is because bones begin to heal very quickly after a fracture and the bone tissue will heal using any tissue available. This can lead to a misalignment of broken pieces of bone and cause disability and loss of function.

There are cases when X-ray may not show a fracture. This is especially common in fractures in the hip and wrist in older people. For diagnosing these, doctors will get some other tests done such as a computed tomography (CT) scan, magnetic resonance imaging (MRI), or a bone scan.

Treatments
Fractures have to be treated by doctors. The doctors set the fractured bones in their proper place and hold them there so that they can heal. Setting a bone is called "reduction." Reduction without surgery is called "closed reduction." But if the fracture is serious, it s going to require surgery with bone repositioning, called open reduction.

In extreme cases, pins, plates, screws, rods, or glue are used to hold the fractured bones in place, inside the body. Once the bone abutment has been treated, the bone is immobilised to allow the broken pieces to heal. In most cases, the fractured part is set in a rigid cast. The fractured ends of the bone can be fixed into place using metal pins connected to an external frame. This is removed after the bone has healed.

Fractures - How To Diagnose Them?

If you are having a chronic cough and often pant for breath, it is quite possible that you may be suffering from bronchitis. In addition to this, you may also experience wheezing, fatigue, and pain in the chest. It is triggered when the lining of the airways in the lungs become irritated. To determine, whether or not bronchitis is contagious, it is important to understand what caused the ailment.

Chronic bronchitis: This type of bronchitis happens when the airways get continuously irritated. It may last for months or even years and tend to come back. It is caused by irritants that affect the lungs such as dust, chemicals, smoke, fire, and smoking cigarettes. Even though chronic bronchitis is not considered contagious, it is a serious health issue that requires medical attention.
Acute bronchitis: It generally lasts for about 1 to 3 weeks and stems from cold or flu virus. As these infections are contagious, so is acute bronchitis.
Whether a person having bronchitis can spread the disease depends on the virus that is causing the ailment. In most instances, it is seen that the disease is contagious for a first few weeks of infection. Since there are hundreds of viruses causing bronchitis, it is best to assume that a person is bound to spread the disease when he has symptoms of cold and flu.

What causes transmission of bronchitis?
Acute bronchitis owing to infection is generally transmitted via an airborne droplet containing germs. It is transmitted when someone having infection shakes hand or sneezes or coughs or has any other physical contact. Some virus and bacteria have the power to live outside the body for a prolonged span of time, and therefore, you can get infected by touching any object that is harboring the germs.

It is often seen that acute bronchitis begins as flu and therefore, the best way to prevent it is to get an annual shot of flu. When you come in contact with an infected person, the chances of being affected is high if you have chronic infections or weak immune system. Aged people and young children are most vulnerable to this disease.

How can acute bronchitis be prevented?
Even though acute bronchitis is extremely common and can occur at any time, winter is the most vulnerable season for bronchitis. But there are ways in which you can prevent bronchitis effortlessly. You should avoid close contact and sharing of utensils with an infected person who has flu, cold or bronchitis. You should not touch a used tissue since the virus of bronchitis can easily spread through mucus. Make sure that you get the annual flu shot and wash your hands in warm water.

The disease is very common, and it can make you feel very uncomfortable at times. But there are times when the symptoms subside on their own without any sort of medical attention.
