How Stress Affects Your Digestion

It can be seen that denying amino acids to bacteria above could be very advantageous in a serum infection. However, the inverse generalized stimulation of protein synthesis44, p.273 [I’m not certain how generalized it is] could have additional survival rationale against digestive disease. 40% of the protein synthesis is in the intestines of the rat, much of it for synthesis of IgA.47 IgA acts as an inert, nonlethal coating on bacteria to prevent adhesion to intestinal walls47 and is the predominant immunoglobulin in the human intestine.43, p.597 Its production depends on the vitamin A metabolite retinoic acid 105. Mora, et al discus how specialized B cells from lymphoid tissue associated with the intestines migrate to the intestines’ wall where interleukin 5 and 6 peptide hormones permit retinoic acid to stimulate secretion of IgA112, p1160. This is no doubt the reason why vitamin A supplements decrease mortality from diarrhea by 34% in malnourished children112.

Urinary urea excretion decreased by 40% over the 6-h study period. Stress can have significant impact on a woman’s reproductive plans.

This can be caused by estrogen therapy and pregnancy. A high circulating concentration of estrogen is the most common cause of high cortisol levels in women. Corticosteroid medications used to treat asthma, arthritis, certain cancers, and other conditions can also cause high cortisol levels when taken in high doses or for a long period of time. Your adrenal glands are located above each kidney.

A, Determination of phenylalanine, tyrosine, and glucose kinetics. The experiment consisted of a fasting 180-min (basal) period followed by a 180-min hyperinsulinemic, euglycemic clamp.

Glucocorticoid mobilization for fight or flight is an adjunct, made possible because most processes which resist infection impair fight or flight. A different hormone controls those which do not.

That means that to conserve energy, important bodily functions such as digestion and tissue repair are delayed while your immune system and reproduction go on “slow-mo”. your brain and body don’t register the difference between a true health threat (a poisonous snake crosses your path) and a flip out over something in your day (your computer just shut down due to a virus). It treats that argument with your partner, social anxiety at the dinner party and overwhelms you feel about your ‘to do’ list the same as if your life was under threat from a pack of hungry wolves. Your adrenals are two walnut-shaped glands that weigh about 0.2

Hyposecretion, or cortisol deficiency, can result from damage to the adrenal glands. This damage can cause Addison’s disease.

Cortisol also forces the breakdown of stored proteins into amino acids so that the body can use them for making enzymes or repairing cells. Cortisol increases blood pressure, which increases blood flow and distributes the glucose and other nutrients as quickly as possible to the cells. Cortisol’s main function is to save us when we are under stress. Cortisol does this by provoking the cell to manufacture glucose from proteins and fatty acids. This process is known as gluconeogenesis.

When you’re meeting a huge deadline for work or you’ve been up all night with a very sick child, you enter this first adrenal phase for a short period of time. Elevated stress hormones initially power you up with energy and then drop you down, leaving you feeling more worn out than usual. But your body is still able to make all the hormones it needs to respond to stress effectively and to energize you to get through the day. A cortisol test may be requested if your doctor observes symptoms suspicious of Cushing’s syndrome (high blood pressure, obesity, muscle wasting, and muscle weakness) or Addison’s disease (low blood pressure, weakness, fatigue, increased pigment on the skin among others). Because of the variety of factors which influence cortisol concentration within the blood, a single measurement is not usually sufficient.
