Eyestrain or eye fatigue has become common place in everyday life for many of us. Most of the time it is nothing more than an annoyance but for some people it can be quite debilitating. Fortunately eyestrain does not lead to any permanent complications but the symptoms may recur on such a frequent basis that it affects a person’s life and even their ability to work. Eyestrain is often a result of ignorance rather than just being overworked. A few simple measures that will take only a few minutes can prevent eyestrain, even amidst a busy work schedule.

Glucose is the basic fuel used by the cells of the body to produce energy. Although the body stores some glucose as glycogen and can use fat and even protein for energy production, we largely depend on a constant glucose supply from food. As the blood glucose levels drop to lower levels, a person feels tired, irritable, sleepy and has difficulty concentrating.
Normally the body keeps the glucose levels in the blood within a narrow range. This ensures that blood glucose levels does not drop to dangerously low levels in a healthy person. But even at lower levels within the normal range, a person may experience symptoms that we tend to attribute to hunger and low blood glucose levels.
The neck is one of the most flexible parts of the human body allowing the head to move in many directions. It is highly muscular part of the body with only the vertebrae at the back providing stability. When the neck flexibility decreases, we often call it a stiff neck. Usually there is pain which worsens with moving the head and neck. Neck stiffness affects almost every person at some time or the other in their life. In most instance it is acute and passes in a few days with minimal treatment. Chronic cases need proper diagnostic investigation and medical treatment as there may be serious underlying muscular, joint and bone problems.
Bed bugs are tiny insects belonging to the Cimicid family of parasites. These bugs survive by feeding on the blood of mammals like humans. The most common of the bed bug species is Cimex lectularius which has a preference for human blood. These insects are commonly referred to as bed bugs as they tend to hide in mattresses, headboards and bed frames during the day. They emerge at night to feed on sleeping human hosts. The oval-shaped adult bed bug is about 4 to 5 millimeters long and up to 3 millimeters wide. It has a light brown to reddish brown color.
Bed bugs feed for between 3 to 10 minutes on a person. After fully feeding it becomes engorged and then retreats. Usually bed bugs live in close vicinity to humans but does not reside on the human body. Its bite and subsequent feeding causes red spots on the skin which are usually orientated in a line or clusters. The site of the bite is typically itchy. Bed bugs more often feed on the face, neck, arms and hands and to a lesser degree on the legs. It can feed at any site on the body and the location of the bite depends on where it can easily gain access and the warmth of the area.
Itching of the groin is as common as itching anywhere on the body. For most of us it is an occasional itch that quickly subsides and is not a persistent problem. An itchy groin is often more distressing than itching elsewhere on the body largely due to social component of it being unacceptable to scratch or touch the groin in public. However, many of the same causes of itching at other sites of the body are also responsible for an itchy groin except for sexually transmitted diseases (STDs) which are often isolated to the groin area.
Why does the groin itch?
Firstly it is important to understand the area that the word ‘groin’ refers to. The groin is actually the crease between the torso and thighs on either side of the genitals. However, most people refer to the groin as the entire lower pubic area, including the crease, genitals and upper parts of the thigh. Commonly the groin is thought to be the area at the front of the body that is covered fully by underwear.
Ear infections are common, especially in children, but many cases of outer ear infections can be prevented with a little vigilance. The ear like any part of the body has various mechanisms in place to prevent infection apart from the fact that the immune system can fight off an infection when it occurs. As the age old saying goes ‘prevention is better than cure’ and a few simple measures are sometimes all that is necessary to prevent an ear canal infection.
The ear is a complex organ that is made up of several structures. It extends well beyond the outer appendage that we see on the side of the ear (auricle or pinna). The ear is actually divided into three parts, the outer, middle and inner ear. The outer ear starts from the auricle (pinna), extends to the ear canal and ends at the outer surface of the eardrum. An outer ear infection can involve any of these parts but most commonly involves the ear canal.
Acid reflux is the most common upper gastrointestinal problem in people across the world. It occurs when the acidic stomach juices flow upwards into the food pipe (esophagus) and sometimes even as high as the throat, mouth or even nose. We all may experience acid reflux every now and then in life especially after overeating and heavily indulging in alcohol or spicy foods. But sometimes the condition is chronic meaning that it occurs non-stop or recurs on a very frequent basis. Acid reflux is more correctly known as gastroesophageal reflux disease. This means that it is a disease where the stomach (gastro-) contents flows backwards (reflux) into the food pipe (esophagus).
We do not often pay much attention to the complexity of human blood but it is a lot more than just red fluid flowing through the blood vessels. Within blood is a host of different cells, carrier proteins, nutrients, gases, wastes and toxins. Blood is the medium through which all these different substances travel from one part of the body to another. If any component of blood is lacking or defective then certain essential processes throughout the body will be disrupted. One such problem is anemia.
Most of us think that we will be able to spot a heart attack when we see one. The typical image of a person clutching their chest, gasping for air and falling to the ground is the way we have seen heart attacks portrayed time and again in the media. Pretty easy to spot even if you have absolutely no medical training. But you may be totally off the mark. A recent study in Iceland has shown that typical heart attacks are far less common than atypical heart attacks (silent heart attack).
In fact, some of the symptoms that we think is due to a heart attack may actually have nothing to do with the heart. Everyday emergency rooms around the world are faced with patients who think that they are having a heart attack but are actually experiencing severe episodes of indigestion and heartburn, among other non-cardiac causes of chest pain. Nevertheless, there is no harm in being cautious especially if you are in a high risk category for having a heart attack.
Falling asleep may seem like an easy task for many but not every person can easily do something that seems so natural. About 1 out of 3 American adults have experienced some difficult in falling asleep and remaining asleep in the past year. As many as 1 out 10 people have chronic insomnia yet only 5% of these people actually seek medical assistance. Sleep problems have a wide array of effects. Not only do you feel tired and less productive but chronic sleep problems can affect every aspect of a person’s life from work to academics and even interpersonal relationships. Difficulty sleeping is a medical problem that can be a sign of some underlying disease. Yet not every person who experiences a sleeping problem has a medical condition that could be causing this disturbance.
There is no denying that modern life has many stresses – physical, mental and emotional – which have a major role to play in sleeping problems. These days money worries and relationship problems are some of the more common mental and emotional stresses that can affect sleep. But not every person with these same stressful factors experience sleeping problems. The question is often “why can’t I asleep” rather than asking “how can I sleep”. As the hours wile away and you are staring at the ceiling until sunrise, try to look at constructive ways not to experience another sleepless night. Simple measures can make a big difference and each person is different. Understanding your body and sleep habits is important to get a good night’s sleep.
Losing weight should be a priority for every person who is overweight or obese irrespective of their age. Similarly maintaining a healthy body weight is a constant undertaking. Both weight loss and weight management are due to the balance of calories – the calories consumed in foods and the calories burned through physical activity. There are various other factors that contribute to weight gain but in the end, being overweight or obese is primarily due to consuming more calories than required by the body on a daily basis.
There are new weight loss fads and slimming diets that are constantly emerging. Some are based on sound scientific principles while others are not. Similarly, some are very effective in assisting a person to lose weight. All too often though, there are fad diets that utilize extreme practices and may only help a person shed a few pounds for a short while but thereafter the pounds return and sometimes even a little more than the original weight. Poor decisions in terms of weight loss programs largely stems from misconceptions, myths and mistakes.
A burning sensation in the feet is a symptom that not entirely uncommon. For most of us who experience burning feet every now and then, the sensation is short-lived and often associated with a long day of standing or excessive walking. Soaking the feet in a warm bath, resting it and even a gentle massage quickly relieves the burning sensation. However, there are instances where burning feet is a recurrent or persistent symptom that cannot be clearly attributed to any known reason like sustained physical activity. It may in fact be a symptom of some underlying disease that has not as yet been diagnosed. While the occasional bout of burning feet that eases quickly is not much of a concern, burning feet as a symptom of a disease can be an indication of serious complications developing.
Therefore understanding some of the reasons behind burning feet is important. Here are ten reasons for burning feet with recommended tests and treatments that should only be considered with your doctor’s approval.
Diarrhea is a common symptom that we all experience several times in our life. In most instances it is acute, meaning that it lasts for a few days, and then eases. It may not even require medical treatment and does not tend to recur shortly after stopping. However, there are instances where diarrhea can be persistent and despite our best efforts, it may not stop without medical treatment. There are also various causes of chronic diarrhea which may be a symptom of some underlying chronic disease. Chronic diarrhea needs to be addressed by treating and managing the underlying causative condition. For acute and persistent diarrhea (not chronic), however, there are several measures that can be taken within the home.
With the 2012-2013 flu season being one of the worst in recent years, there is widespread concern about how the flu should be prevented, treated and managed. The fact is that the same medical guidelines that have applied for preceding flu seasons should be followed closely. There is no ‘cure’ for the flu although antiviral drugs like oseltamivir (branded as Tamiflu) and zanamivir (branded as Relenza) have contributed greatly to reducing the severity and duration of the infection and preventing complications. However, the focus on supportive measures is often forgotten such as strict bed rest, plenty of fluids and a balanced diet.
Cholera may not be a major concern for most Americans but it is one of the main diarrheal illnesses that causes over 100,000 deaths per year throughout the world. It had been almost totally eliminated in the United States with the last local outbreak being in 1911. But in recent years, especially after Hurricanes Rita and Katrina, there has been greater awareness about the dangers of cholera.
With only about 10 cases of cholera occurring in the United States every year, it may not pose a major health threat to most Americans. People traveling to endemic areas obviously need to be cautious especially when it comes to food and water. For Americans who do not travel across the border, cholera can still be a risk when consuming seafood that is undercooked, like raw oysters and sushi. Even with seafood sourced from the US or imported fruit and vegetables.
Understanding cholera, the disease and the dangers, whether it is contracted locally or abroad can ultimately be a life and death situation. Up to half of all untreated cholera cases are fatal yet this could be avoided. The fact of the matter is that cholera is easily treatable. In fact it is not the cholera infection itself that is the killer but rather the complications that can be fatal. Dehydration in cholera can develop so fast and be so severe that it can kill an infected person within just a few days.
Meaning of a Full Stomach
What does a full stomach mean?
Full stomach is a common term that most of us use to describe the distention of the stomach usually after eating a meal. The term is not entirely inaccurate although it may sound crude at times. When we eat, the stomach fills and its wall stretches. This is one of the reasons we feel satisfied and the hunger pangs subside. There are other signals that abate hunger as well so a stretched stomach is not always necessary. Therefore one can eat a small meal at times and feel satisfied without the stomach is feeling full.
