in a quickie internet search, i could not find a website that i considered to be medically credible that had an answer to this Q. on the various forums that i looked at, which certainly did not include every food/weight-related forum there is, the consensus seems to be that brewers yeast does not precipitate weight gain.
i'm assuming that you have been checked out medically to make sure there is no physical reason for your being underweight.
with that as a given, here are some other suggestions i've come up with --
**have your thyroid checked. if it is high, you will probably have trouble gaining weight.
**have you considered meeting with a registered dietician for advice on nutritious meals that will help you gain weight? you can find one thru the american dietetic association, http://www.eatright.org/default.aspx .
**you might want to take a look at the "diet" exchange on webMD, http://exchanges.webmd.com/diet-exchange , which i saw has some underweight-related Qs on it. i believe that this is what the previous "underweight support group" turned into.
i'm sorry i didn't see your post until today, and i hope you are still following it.
what has happened since your stomach episode of last week? did it go away; did you see a dr?
my inclination is to say that if you have another episode, particularly if it is close in time to this one, you should consult your dr.
altho i am not a medical person, the way you describe the pain you had, and its location, does not sound as acute and disabling as i think appendicitis would be. however, if you have any doubt, either call your dr or go to the ER.
even tho it is scary to contemplate going to the dr, it is always better to know than to not know. you won't be able to do anything about this unless you first find out what is causing it or what it might be a symptom of.
because of the nature of this pain, the wisest plan might be to see a neurologist.
you can find webMD info pages for any drug by going to the blue bar across the top of the page, hovering over "drugs and supplements," then choosing "find a drug" from the dropdown menu. when you click on that, you are taken to a page where you can enter the name of the drug you are interested in.
i had a wonderful response for you, and somehow i lost it! i'll try to remember everything i said.
i am so sorry that you've been suffering these apparently inexplicable fainting spells (called syncope in medical contexts). it must be esp scary and frustrating to you because of two specialists and your own dr having been unable to figure out why these are happening.
i have several suggestions --
-- have you been tested for seizure activity in your brain?
-- have you been tested for anemia?
-- are you dizzy when walking or just before passing out? if so, you might want to see an ear/nose/throat (ENT) dr to check for balance/inner-ear problems.
-- before these spells began, did you fall and hit your head somehow? is there the possibility that in the first episode of fainting, you hit your head on the way down?
-- what kind of heating system do you have in your house? have you had it checked any time recently for leaks of carbon monoxide? you will have to have a heating/furnace person come to your house to do this.
-- do you eat at regular intervals? do you drink liquid at regular intervals? are you getting enough sleep?
-- have you tested your blood pressure several times/day? these spells could be associated with periods of lowblood pressure that don't get picked up by a one-time test.
-- are you taking meds for high/low blood pressure or for heart problems?
-- is there the possibility that one or more of your meds, esp your psych meds, could be interacting in such a way as to increase their sedating effects on your body? you will need to talk with a psychiatrist, who will know about the various meds you are taking, esp the psych meds, and whether such an interaction might be possible.
-- i ask this previous Q because when i passed out one time, it turned out to be because the dosage on one of my antidepressants was too high, and over time it had built up in my body to a sedation level that was way too high. when i passed out, i evidently hit everything in the bathroom on the way down, breaking my leg and a bone in my back. as a result, i spent two weeks in the hosp, two weeks in rehab, and three months in a wheelchair. i certainly would not want that to happen to you!
-- is there a possibility that this could be related to stress?
-- do you keep your house temp above 75 degrees or so? does your house feel stuffy to you?
-- i think it might help if you kept a sort of diary of when these spells happen, including day and time, where, day, what was happening immediately beforehand, and anything else you think might be relevant. some pattern might make itself known. you could add in comments from other people who were present when you fainted and what they observed.
i hope you can get some relief soon. please keep us posted on how you are doing.
in addition to multitasker's excellent advice, you might want to try to cut down on the amt of walking you do and to keep your ankle elevated when you can -- when you are sitting or lying down, for instance.
have you and your husband considered marriage counseling? it is not always for people whose marriages are in serious trouble; it can also help people learn how to communicate in ways that don't make each other's emotions more instead of less raw. either that or individual therapy would give each of you a safe place to vent and to get some objective feedback on how to handle your day-to-day problems.
altho it has been ten yrs since your husband's fall, your post says basically that his behavior has not been the same since then and that recently it has gotten worse. sudden personality changes can be a sign of brain damage. he needs to be evaluated by a neurologist.
if he has gotten physically abusive, it may be time for you to think about getting out. physical abuse usually gets worse and worse, and altho i'm sure that you don't want to consider this idea, your life may be in danger..
is there a women's shelter in your area? they can advise you on what to do next.
in my PS are several resources for you with respect to physical abuse by your husband.
please write back and keep us posted on how you are doing.
