Dear Lybrateuser, - Your problem could be due to a sudden drop in blood pressure which can occur when standing up from sitting or lying down position - have plenty of oral fluids including 8-10 glasses of water per day - have a well balanced diet with mire if fruits & vegetables (also green leafy ones like spinach, kale, broccoli) - rise slowly from sitting position as suddenly getting up leads to sudden drop of BP leading to giddiness or improper vision - also get your BP checked by a doctor.

Causes, Symptoms and Treatment for Night Blindness

Causes, Symptoms and Treatment for Night Blindness

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. Consult an Expert & get answers to your questions!

Health Benefits Of Carrot Juice

Health Benefits Of Carrot Juice

Carrots are an excellent source of vitamins, nutrients, and fiber. But you don’t have to eat carrots to receive these nutritional benefits. Drinking carrot juice is an easy way to add carrots to your diet. Here are eight reasons why you should add carrot juice to your diet.

1. Stronger vision

It’s often said that eating carrots is good for your eyes. It turns out there’s truth behind this claim. Carrot juice is a good source of beta-carotene, a type of vitamin A, which is one of the most powerful antioxidants.

Vitamin A helps protect the surface of the eye and contributes to strong vision. Drinking carrot juice can ward off various eye disorders, such as macular degeneration, cataracts, and blindness. Carrots also contain lute in, which is an antioxidant that protects the eye from damaging light. 

2. Improved skin disorders

If you have a history of skin problems, such as rashes or psoriasis, adding carrot juice to your diet may improve the appearance of your skin. Carrots contain vitamin C, which has healing properties. It helps skin recover faster from external wounds and trauma. Beta-carotene in carrots also reduces skin inflammation, which speeds the healing process.

3. Boosted immune system

A cold or the flu can stick around for one or two weeks, making it difficult (or impossible) to go to work or school. To strengthen your immune system and help your body fight off infections, add carrot juice to your daily diet and maintain your physical health.

Carrots contain antioxidants, which help your body fight free radicals, cell damage, and inflammation. Vitamin C in carrot juice also provides an immune system boost, helping you get through cold and flu season.

4. Boosted immune system

A cold or the flu can stick around for one or two weeks, making it difficult (or impossible) to go to work or school. To strengthen your immune system and help your body fight off infections, add carrot juice to your daily diet and maintain your physical health.

Carrots contain antioxidants, which help your body fight free radicals, cell damage, and inflammation. Vitamin C in carrot juice also provides an immune system boost, helping you get through cold and flu season.

5. Lowered cholesterol

If you’re having trouble controlling your cholesterol, or if you want to control your cholesterol without medication, consider adding carrot juice to your diet. As an excellent source of potassium, carrot juice can help you maintain a healthy cholesterol level. Lower cholesterol levels reduce your risk of heart disease and stroke. Talk to your doctor before stopping any prescription medications.

Pre & Post Workout Meal - Understanding Its Importance!

Pre & Post Workout Meal - Understanding Its Importance!

Eating the right food at the right time is essential to in order to complete your fitness goal. While there exist many theories on the importance of workout meal, there are some simple rules which when followed can fetch great results. The right amount of nutrition pre and post workout can go a long way in ensuring that the body responds well to the stress.

Why is nutrient timing an important component of the exercise regime?
Consider your body as a machine, it is imperative that a well-maintained machine with the right fuel at the right time will have more longevity compared to others. The same holds true for the body as well. To maximize the output of the gym, it is necessary to consume the right nutrients for the body. A right meal just before the gym session can result in a great workout session. This, in turn, means an inch closer to the fitness goal. Similarly, the post workout meal ensures that muscles are adequately refueled and the blood sugar level is well maintained. Another advantage of the right pre and post workout meal is the fact that it helps the body to work out for a longer duration.

Know the carbohydrate
Instead of blindly choosing an energy drink, it makes sense to choose the right carbohydrate. There are 2 types of carbohydrate- simple and complex. Eventually, all carbohydrates are broken down into simple carbohydrates. Both have their own role to play. As per various studies, it has been proved that the best time to consume complex carbohydrate such as brown rice, oats and brown grains is before a couple of hours of the workout session. It ensures that the body is provided with a gradual supply of energy throughout the session. After a workout session, much of the glycogen gets depleted from the muscles. It is, therefore, essential to consume simple carbohydrate after a gym session. It readily supplies instant energy and carb to the muscles. Some good source of simple carbohydrate includes sugar, candy bar, sweet bread, fruits etc.

The next meal after workout
Post workout, the simple carbohydrate gets absorbed by the body way too fast. It is, therefore, necessary to have a good meal couple of hours after the workout session. Some good to consume food include green veggies, fruit salad etc. It helps in suppressing the appetite and make a person feel full.

What should be the protein count?
While there are many recommendations out there, a good way to determine the protein count is to consume 1.1 gm to 1.2 gm per kilogram of body weight. However, there is no magic number. 25-35 grams of protein needs to be consumed in every meal. Ideally, protein intake should happen a couple of hours before the workout and couple of hours after the workout session. If you wish to discuss about any specific problem, you can consult a Dietitian/Nutritionist.

Conversion Disorder - Know More About It!

Conversion disorder is a psychological disorder in which psychological conflicts get converted into physical symptoms.

The disease is also referred to as a functional neurological symptom disorder. In most cases, this disorder has an impact on your ability to move, your senses, vision, hearing capacity and ability to swallow.

Causative factors

The main cause behind the onset of a conversion disorder is generally a sudden traumatic event (real or imagined). This may also happen due to an emotional conflict or any other mental health disorder, which directly or indirectly affects your brain in an undesirable manner.

Though the exact factors which cause the disease are still unknown, it has been proved by medical researchers that the disorder affects that part of the brain which controls the majority of the senses, muscles, and nerves.

Identification signs

The symptoms of this condition may usually appear immediately after a traumatic event, be it physical or psychological. Some of the most common symptoms of this disorder are listed below.

  • Weakness or paralysis of a body part
  • Loss of body balance
  • Moments of unresponsiveness
  • Abnormal, sudden and abrupt body movements such as tremors
  • Swallowing problems such as lump in the throat

Some of the symptoms of this disorder might also affect the sensory organs, which include:

  • Abnormal numbness of the body
  • Speech related problems or inability to speak (psychological mutism)
  • Vision related problems such as psychological blindness
  • Hearing problems and difficulties

If you wish to discuss any specific problem, you can consult a psychologist.

Amblyopia and Childhood Blindness

Treatment for Amblyopia (lazy eye)

Hi. My name is Dr. Chandrashekhar Kale. I'm a pediatric Ophthalmologist and I'll be talking about Amblyopia and Childhood Blindness.

So when we say about pediatric ophthalmology the most common thing that comes to our mind is Bariatric Cataract and squint but if we look at the most common cause of preventable blindness in children then it's definitely Amblyopia or what we call as a lazy eye. Now Amblyopia is a Neurosensory disorder, that means your eye and brain both the things are involved. It's a condition in which vision in one of the eyes is less because of any focusing problems in your eye which occurred in your early childhood period. Now, this can be due to ocular misalignment which is called as squint or hindrance to light which enters the eye because of ptosis or cataract or can be simple refractive errors, especially the higher refractive errors. Usually Amblyopia is more commonly seen in one eye and hence is very difficult to detect because when the child sees, he sees with both the eyes open so if one eye has got a poor vision and another eye is good, the child will not be able to identify that he is not able to see with one eye unless he closes one of the eyes. So here comes the importance of early screening of the eyes.

As far as the treatment of Amblyopia is concerned, it is mostly treating the pre-depositing factors like squint or cataract where it's a surgical intervention or you can do a simple refractive error check up and glasses prescription. One of the most important factors for Amblyopia management is the exercises for lazy eye. The most common is the patching exercises where in you close the good eye and the child is forced to see from the poor eye. The principle behind this is once the child sees from the poor eye for a period of time your brain will get accustomed to see through the poor eye and gradually over a period of time visual improvement occurs in the eye. The only thing here is that the exercises, as well as the treatment, has to start before 8yrs of an age where in you can expect a complete recovery of the vision. Here, at our institute, we have a special device or software called the Vision Therapy software which is aimed for the improvement of vision in your Amblyopic eye.

This is basically a computer generated device where in some exercises are given via computers. Now since this is given by computer and designed in form of some small games the compliance in a child is much better as compared to the regular patching exercises. So, definitely, the visual improvement is much faster with this new computer generated exercises. So in a nutshell what I would like to say is that Amblyopia is definitely preventable, especially if you diagnose it at an early stage. We need more awareness regarding this condition, in the parents, in the public, also in the pediatrician so that the child gets his first eye check up as early as possible, preferably by three yrs of age. This is what I wanted to say about Amblyopia and treatment of lazy eye in a nut shell.
