What is the difference between a symptom and a sign?

A symptom is any subjective evidence of disease, while a sign is any objective evidence of disease. Therefore, a symptom is a phenomenon that is experienced by the individual affected by the disease, while a sign is a phenomenon that can be detected by someone other than the individual affected by the disease. For examples, anxity, pain, and fatigue are all symptoms. In contrast, a bloody nose is a sign of injured blood vessels in the nose that can be detected by a doctor, a nurse, or another observer.

Health-care professionals use symptoms and signs as clues that can help determine the most likely diagnosis when illness is present. Symptoms and signs are also used to compose a listing of the possible diagnoses. This listing is referred to as the differential diagnosis. The differential diagnosis is the basis from which initial tests are ordered to narrow the possible diagnostic options and choose initial treatments.

Our Symptom Checker for children, men, and women, can be used to handily review a number of possible causes of symptoms that you, friends, or family members may be experiencing. There are many causes for any particular symptom, and the causes revealed in the symptom checker are not exhaustive. That is, they are not intended to be a listing of all possible causes for each symptom but are representative of some of the causes that can be underlying various symptoms.

Think it’s your empty stomach that causes hunger? That’s not the whole story. Hunger is a complicated process that all animals experience in order to maintain the energy necessary to stay alive. And it involves more than just the stomach.

Some hunger triggers do start in the stomach. Nerves react to a full stomach, and can signal the brain to slow or stop eating. But much of the process we think of as hunger and fullness comes from a tiny region at the center of the brain known as the hypothalamus. This part of the brain receives chemical signals for fullness and hunger, and sends chemical responses to regulate those feelings.

Hunger can be triggered by many things. It may be a billboard featuring steaming croissants that makes your mouth water. It may be the time of day—many people get hungry around noon if that’s when they take their lunch. It may also be a matter of habit; if you eat in front of the TV frequently, turning on the tube could trigger hunger for you. Or your body may simply need calories.

In the following article, explore the causes of hunger. Learn what makes you want to eat, and how to control those triggers to avoid the harmful effects of overeating, which include obesity and related diseases such as heart disease and diabetes.

Attitude Is Everything

Be Positive to Boost Immune Response

Expect good things and your immune system will follow. A study of law students found that their immune systems were stronger when they felt optimistic. Make optimism work for you. Try to see the glass as half full, not half empty. Practice gratitude and think of at least three things that you are grateful for every day. Imagine the best outcome for situations, even difficult ones. You may not always be able to control events around you, but you can always decide how to respond to them. Respond with a good attitude to increase the chances of the best outcome and to strengthen your immunity.

Can Sex Boost Your Immune System?

Regular Sexual Activity Is Helpful

In a study of college students, those who had sex once or twice per week had the highest levels of immunoglobulin A (IgA) in their saliva. IgA is an immune molecule that helps protect us against illnesses like the common cold. Students who had sex once or twice per week had more salivary IgA than students who were not sexually active, infrequently sexually active (less than once a week), or who were very sexually active (three or more times per week). Enjoying sex up to a couple of times per week seems to be the sweet spot for promoting optimal IgA levels.

Is Stress Bad for You?

Chronic stress depresses the immune system and increases the risk of several types of illnesses. It raises the level of hormones called catecholamines. Being stressed out leads to increased levels of suppressor T cells, which suppress the immune system. When this branch of the immune system is impaired, you are more susceptible to viral illnesses including respiratory conditions like colds and flu. Stress leads to the release of histamine, a molecule involved in allergies. Combat stress with strategies like deep breathing, meditation, exercise, and relaxation.

"We have to listen with love to Our body's Messages".


I listen and realise my body's message. Are you do this?.

 You believed or not all of us create every  so - called illness in our body. The body, like everything else in life, is a mirror of our inner thoughts and beliefs. The body is always talking to us, if we will only take the time to listen. Every cell within our body responds  to every single thought we thinking and every word we speak.

   Continuous modes of thinking and speaking produce body behaviors and postures and "eases" or de - ease. The person who has a permanently scowling face did not produce that by having joyous, living thoughts. Older people's faces and bodies show so clearly a life time of thinking patterns. How will you look when you are elderly?.

   Here is few example of probable Mental Patterns that create illnesses in the body as well as the New Thought Patterns or Affirmations to be used to creat health.

     1) The Ears
                Represent  the capacity  to hear. When there are problems with the ears, it usually means something is going on you do not want to heare. An earache would indicate that there is anger about what is heard.
      Earaches are common with children. They often have to listen to stuff going on in the household they really don't want to hear. Household rules often forbid a child's expression of anger, and thebchild's inability to change things creates an earache.
   Deafness represents longstanding refusal to listen to someone. Notiethat when one partner has a hearing impairment, the other partner often talks and talks and talks.

      2) HEADACHES 
 Come from invalidating the self. The next time you get a headache, stop and ask yourself where and how you have just made yourself worng. Forgive yourself, let it go, and the headache will dissolve back into the nothingness from where it came.

    Migraine headache are created by people who want to be perfect and who create a lot of pressure on themselves. A lot of suppressed anger is involved. Interestingly, migraine headaches can almost always be alleviated by masturbation if you do it as soon as you feel a migraine coming on. The sexual release dissolves the tension and the pain. You may not feel like masturbating then, but it certainly is worth a try. You can't lose.

Anorexia Nervosa. !!!

The self-starvation that is a hallmark of anorexia nervosa is caused by a complex psychiatric disorder.

It is estimated to occur in approximately 0.5% of Australians and New Zealanders, mostly adolescent girls or young women.  

(Only about 10 per cent of people with anorexia are males; they are often weight-conscious adolescent boys who are dancers or athletes.)
  The cause of anorexia nervosa --
A medical term for a relentless pursuit of extreme thinness and refusal to eat so as to maintain normal weight ---is unknown. Researchers belive that a combination of hormonal, social and psychological factors are responsible. The disease often begins in adolescence, a time of hormonal and psychological change. Convinced that she is too fat, regardless of how much she actually weight, a girl beings obsessive dieting. Some girls adopt a very restricted diet while others become overly preoccupied with food, often planning and preparing elaborate meals that they then refuse to eat. When the girl with anorexia does eat, she may resort afterwards to selfimduced vomiting or laxative abuse to avoid gaining weight. Many also exercise obsessively.

  Take note of telltale signs. --
   
   As the disease progresses, menstruation ceases and nutritional deficiencies develop. Many girls with anorexia try to hide their thinness by wearing oversized clothes; physical indications of anorexia include fatigue, nervousness or hypersctivity, dry skin, hair loss and intolerance to cold. More serious consequences include cardiac arrhyrhmias, loss of bone mass, kidney failure and in about 6 per cent of cases, death.

CONSUME --

• A Variety of nutritious foods in small amounts.
•  High-protein liquid supplements and   multivitamin  supplements, if approved by   a doctor or dietitian.

AVOID --

•    Diet soft drinks and low-kilojoule or low-fat diet foods.
• Appetite suppressants, diuretics and laxatives.

C  A  U  T  I  O  N : -

 Younger women are particularly vulnerable to eating disorders like anorexia nervosa, a serious, often chronic and life-threatening condition. Although the term 'anorexia ' literally means loss of appetite, people with anorexia nervosa actually ignore hunger and deliberately control their desire tobeat.

   Constant obsessive dieting may result in severe anorexia and sufferers may be at risk of death from starvation.

   Should someone you know exhibit the following warning signs, contact a doctor knowledgeable about eating disorders immediately.

• Preoccupation with food
• Distorted body image, thinking they are fat when they are actually bone-thin
• Intense fear of gaining weight
• Refusal to eat
• Deliberate self-starvation
• Denial of hunger
• Obsessive exercise
• Loss of scalp hair
• Brittle nails and hair
• Constant complaining about feeling cold (due to low body temperature) 
• A fine layer of hair on the body or face (like on a newborn baby)
• Depression
• Irregular or absent periods.
