why doesn't deficiency of riboflavin, lead to disease?

do you want some disease???? maybe you should have some just to justify your desire for some.

Riboflavin Deficiency
Further information: Ariboflavinosis
A deficiency of riboflavin can be primary - due to not getting enough of the vitamin from the diet - or secondary, which may be a result of conditions that affect absorption in the intestine, the body not being able to use the vitamin, or an increase in the excretion of the vitamin from the body..

In humans, signs and symptoms of riboflavin deficiency (ariboflavinosis) include cracked and red lips, inflammation of the lining of mouth and tongue, mouth ulcers, cracks at the corners of the mouth (angular cheilitis), and a sore throat. A deficiency may also cause dry and scaling skin, fluid in the mucous membranes, and iron-deficiency anemia. The eyes may also become bloodshot, itchy, watery and sensitive to bright light.

In animals, riboflavin deficiency results in lack of growth, failure to thrive, and eventual death. Experimental riboflavin deficiency in dogs results in growth failure, weakness, ataxia, and inability to stand. The animals collapse, become comatose, and die. During the deficiency state, dermatitis develops together with hair-loss. Other signs include corneal opacity, lenticular cataracts, hemorrhagic adrenals, fatty degeneration of the kidney and liver, and inflammation of the mucus membrane of the gastrointestinal tract. Post-mortem studies in rhesus monkeys fed a riboflavin-deficient diet revealed that about one-third the normal amount of riboflavin was present in the liver, which is the main storage organ for riboflavin in mammals. These overt clinical signs of riboflavin deficiency are rarely seen among inhabitants of the developed countries. However, about 28 million Americans exhibit a common ‘sub-clinical’ stage[citation needed], characterized by a change in biochemical indices (e.g. reduced plasma erythrocyte glutathione reductase levels). Although the effects of long-term sub-clinical riboflavin deficiency are unknown, in children this deficiency results in reduced growth. Subclinical riboflavin deficiency has also been observed in women taking oral contraceptives, in the elderly, in people with eating disorders, and in disease states such as HIV, inflammatory bowel disease, diabetes and chronic heart disease. The fact that riboflavin deficiency does not immediately lead to gross clinical manifestations indicates that the systemic levels of this essential vitamin are tightly regulated.

In addition to it, what food I should take more to meet the deficiency. I have no other health problem. I am regularly doing physical exercises for the last 10 years. I wonder how it happened? can any expert please explain?
Hyperthyroidism is characterized by hypermetabolism and elevated serum levels of free thyroid hormones. Symptoms are many but include tachycardia, fatigue, weight loss, and tremor. Diagnosis is clinical and with thyroid function tests. Treatment depends on cause.(Merck)
Major clinical signs of Hyperthyroidism include weight loss (often accompanied by a ravenous appetite), anxiety, intolerance to heat, fatigue, hair loss, weakness, hyperactivity, irritability, apathy, depression, polyuria, polydipsia, and sweating.(Wikipedia)
Methimazole is used to treat hyperthyroidism, a condition that occurs when the thyroid gland produces too much thyroid hormone. It is also taken before thyroid surgery or radioactive iodine therapy.(MedlinePlus)
Methimazole and propylthiouracil are used to treat conditions in which the thyroid gland produces too much thyroid hormone.
These medicines work by making it harder for the body to use iodine to make thyroid hormone. They do not block the effects of thyroid hormone that was made by the body before their use was begun.(MayoClinic).  (+ info)

How does iron deficiency affect the composition of blood?

---

I have a good friend who is diagnosed with iron deficiency, although she is getting better i want to know more about her sickness. Please answer.
Iron deficiency makes it harder for your blood to provide oxygen to your body. So you could feel tired or out of breath. It's not that uncommon in women. I think, but do not know, that's it's because they have to replace the menstrual loss every month. There could be other more serious problems causing the deficiency - ask your friend about the diagnosis.

Iron-poor blood is less dense than iron-rich. When you donate blood, they'll put a drop into a special solution to see if it sinks. If it floats, there isn't enough iron. If it sinks like a rock, there's plenty.  (+ info)

What deficiency is it when you see bright dots flying in front of your eyes?

---

I mean when I are just not exactly looking at anythign in particular but you see bright dots/sparks flying away near your line of vision.

Weird? I thought so.But I figured this is a kind of deficiency.I remembered seeing this during pregnancy.I was anaemic then?Does this mean I am anaemic?

April.
I thought floaters were usually dark.
My Mom had the sparks once and was told to get to a Dr. to have her eyes checked immediately. Sometimes this is an indication of something happening within your eye. I can't remember for sure but I think it has something to do with the retina separating?
Anyhow....check it out. Perhaps it is more substantial at my mom's age, but it's better to be safe then sorry!
All the best!  (+ info)

What deficiency may be the cause of my strange food craving?

---

I am wondering if anyone knows if this is a sign of a vitamin and/or mineral deficiency, and if so which ones? Lately, I've had this thing for English muffins topped with cream cheese and pickles??? Maybe just stress? I'm sure I'm not pregnant (on birth control), but I have heard that strange food cravings can mean that your body is lacking something. Does anyone know?
stress can be a big factor, yes. You may also not be consuming enough fats or sugar, but this doesn't mean you have to overdo it. Did you eat enough in the past days?  (+ info)

What makes iron deficiency anaemia different to other types of anaemia?

---

what is special about it to make it 'iron deficiency' anaemia? What are other types of anaemia like?
Ronnie - Iron is needed in the body to make hemoglobin which gives blood the red color and allows the red blood cells (RBC) to carry oxygen to all body tissues. The most common cause of anemia is a deficiency of iron in the diet. It can also be caused by a vegetarian diet (with no red meat) or by loss of blood from bleeding of any cause. Sometimes iron may be plentiful in the normal bone marrow where RBCs are made, but the body is 8unable to use the excess iron to make RBCs. Other types of anemia exist. In old age, the number of RBCs made in the bone marrow is replaced by fibrous tissue and anemia of aging occurs. Some chemicals can cause a break-up of normal RBCs (a hemolytic anemia). Some genetic or hereditary causes include sickle cell anemia or thalassemia. Some infections cause anemia like malaria where the parasite invades and destroys red cells. So, really, the only thing that makes iron-deficiency anemia different is that it is the most common and most-talked about type of anemia. Fortunately, it is also the easiest to treat successfully.  (+ info)

How do the white flecks in fingernails indicate a calcium deficiency in the body?

---

A beautiful, unforgotten, and very helpful friend once told me that the white flecks and spots in my fingernails indicate a calcium definciency in my body. I've been taking calcium everyday for years. How is it that I have a calcium deficiency?
It's a common medical myth that white spots on your fingernails are caused by too little calcium in your diet. However, these white spots (called leukonychia) are not a sign of a calcium deficiency. But they can be an indicator of other problems.

The most common cause of leukonychia is blunt trauma to the nail bed, such as a knock or a blow. Due to the slow growth rate of nails, the white spots of leukonychia may appear gradually and linger for months.

Other causes could include a rough manicure, a slight allergic reaction to enamels or other nail products, or even a mild bacterial or fungal infection.

White spots can also appear on toenails, but regardless of their location, they are generally harmless and will disappear with time. However, a nail that turns completely white could be a symptom of liver disease and should be looked at by a doctor. http://www.soundmedicine.iu.edu/segment.php4?seg=204
