Re: Blood Donation Frequency

[Guest guest]

if your posting this because your on TRT and your blood it to think giving

blood helps with this problem. But one should not do this to often if not

needed you can end up with low Ferritin and Iron levels. Only give blood when

your blood labs show you need to. Also get on some Fish Oil get a script from

your Dr. for it so you know your getting good stuff this helps keep blood thin

and do a baby aspirin every 12 hrs.

I posted this information because someone mentioned that they gave blood once a

month. That appears to be to often for whole blood donation. The blood bank of

Iowa makes you wait 8 weeks for a pint of whole blood, 16 weeks for a double red

cell donation. I believe you can donate plasma every 2 or 3 days. " "

When I donate blood, 7 Gallons so far, They always test my iron before the

donation.. It has never been too low.

That it great as long as they or your Dr. is testing Total Iron

Iron Binding Capacity

Iron % Saturation

Ferritin

B-12

Men doing this to keep there blood thin some end up with low Ferritin levels and

this is not good I have need down this road but not from giving blood.

Here is a cut and paste on what Dr. M says about this.

--------------------------------------------------------------------------------

SOME IRON FACTIODS:

The average adult male has about 4.5 grams of iron in the body.

Iron is distributed in six areas of the body:

Hemoglobin - about 3000 mg (66.4 %)

Myoglobin - about 160 mg (3.5 %)

Storage Iron (Ferritin, Hemosiderin) - about 1125 mg in men (25 %), 650 mg in

women

Tissue Iron - about 110 mg (2.5%) This includes ron-containing enzymes such as

the cycochromes, peroxidases, catalse, oxidases, dehydrogenases

Transport iron (transferrin) - about 4.5 mg (0.1 %)

Labile Iron pool - about 110 mg (2.5 %). This is ion that is temporarily bound

to cell membrane or cytoplasmic proteins before being incorporated into heme,

enzymes or other structures

The body can only absorb about 1 mg out of every 20 mg of iron in food consumed.

Ferric iron is not absorbable

Ferrous iron is absorbable

Total daily iron loss is

about 1 mg/day in 70-kg men and

0.8 mg/day in 55-kg non-menstruating females,

1.2 to 3.4 mg/day in menstruating females

USA Food and NUtrition Board Recommended daily allowance of iron:

Adult males 8 mg/day,

adolescent males 11 mg/day,

adult females premenopausal 18 mg/day, adult females postmenopausal 8 mg/day,

adolescent females 15 mg/day,

pregnant females 27 mg/day

Vegetarian diet contains less absorbable iron.

The adjusted US RDA adjusted for vegetarian diet is:

men 14 mg/day,

postmenopausal women 14 mg/day,

premenopausal women 33 mg/day,

adolescent females 26 mg/day

Regular intense exercise increases iron requirements by about 30%.

1 Unit of Blood contains 250 mg iron.

1 unit blood donation in susceptible women, 3-4 units of blood donation in men

may exhaust iron stores.

CAUSES OF IRON DEFICIENCY:

Iron deficiency may occur from the sum of iron intake and iron losses as

follows:

INADEQUATE IRON IN FOOD

Minerally deficient farmland leads to mineral deficient fruits and vegetables

Lack of meat, seafood - both promote absorption of non-heme iron. Meat provides

well-absorbed heme iron.

Vegetarian diet - iron from plant sources are less efficiently absorbed

POOR ABSORPTION OF IRON

Diarrhea

Malabsorption Syndrome (e.g. gastric bypass)

Hiatal Hernia

Celiac Disease

Inadequate Gastric Acid (improves iron absorption by converting ferric iron to

ferrous form)

Aging

Antacid use (reduces absorption of iron, zinc, etc.)

Coffee/Caffeine (causes loss of B-vitamins, Vitamin C, calcium, iron and zinc)

Inadequate Vitamin C (improves iron absorption by converting ferric iron to

ferrous form)

Inadequate sugar (glucose, fructore), amino acids, succinates (these bind to

iron and facillitate binding to intestinal mucosa, which absorbs the iron).

Excess pancreatic alkaline secretions (convert ferrous iron to inasorbable

ferric form)

Dietary phosphates in cereals bind to iron and prevent absorption

Phytates (inositol hexaphosphate salts) are in grains, seeds, nuts, vegetables,

roots (e.g. potatoes), and fruits

High phytate content: bran, whole-wheat flour, oats.

Coffee, Tea, Cocoa contain Polyphenols (such as tannin), which bind to iron,

preventing absorption

Calcium competes with iron for absorption. Maximal inhibition of iron is 60% by

300-600 mg of calcium in a meal.

Fermented vegetables - enhance iron absorption

Red wine (most) contain phenolic compounds which bind iron and inhibit

absorption

Certain medications impair iron absorption (e.g. Tetracycline)

BLOOD LOSS

Gastrointestinal bleed (more than 50 causes)

Aspirin, Ibuprofen and other NSAIDS)

Ulcerative Colitis

Gastric Ulcer

Hook Worm

Colon Cancer

Hemorrhoids

Hereditary Hemorrhagic telangiectasia (Osler's disease)

Renal loss (hematuria,

Menstruation

Fibroids

Endometriosis

Post-partum hemorrhage

Dialysis

Hemolysis

Malaria

G6PD deficiency

IUD Use

Intense Exercse (e.g. marathon running).

Exercise decreases intestinal blood flow by 20-50%,

Decreased blood flow increases the risk of ischemic damage to the stomach and

intestin.

Exercise also decreases lower esophageal sphincter pressure, increasing the risk

of erosive esophagitis.

Running may traumatize gastrointestinal organs and increase the risk of bleeding

from hemorroids.

PHYSIOLOGIC LOSS OF IRON

Menstruation

Sweat

Urine

Bile

Loss of skin cells

Loss of cells from mucosal membrane, stomach, and intestines.

INCREASED IRON REQUIREMENTS

Growth (expansion of the total body iron body)

Pregnancy and lactation

I just got cleared to be a donor again after having metastatic lung cancer 7

years ago. At that time you were banned for life but now their thinking has

changed. I believe if you are cancer free for 5 years you can donate again.
