Well, onto more personal issues!
I haven’t stopped obsessing about this osteoporosis stuff. I’ve tried to research it the best I can. I don’t have osteoporosis YET. However as much as I try to keep the wolves at bay, I know I am sliding and I have a little time in which I can hopefully stall progress to the full blown mcoy & I want to go there yesterday!
It’s not that nothing is being done about my situation. I’m just impatient as usual. I am being well monitored currently with frequent labs and yearly dexa’s. My lab situation is as follows regarding calcium : Vit D is normal, PTH is normal, calcium was a little low, for the first time in all the time I have been a DSer. I’m supplementing appropriately & in traditional DS ways daily, calcium citrate and magnesium & Vit D plus plus!. But due to a genetic propensity for osteoporosis in my family, I have a more complex bone story than most DSers. In the next three months or so I may be seeing a bone specialist with whom I will discuss the in’s and out’s of what I discuss below.
I stress that what I write is speculative and highly layperson, that’s the nature of many blogs. My bloggings are largely intended to (hopefully) sort my own stuff out and reflect how I do this via constant enquiry. I don’t believe enquiry and questing for more new knowledge ever hurt anyone. I believe we all need to do this when we have a major surgery, imo - it comes with the territory. That said, bone metabolism is serious stuff. Think about it, do even more research using various sources, do your own enquiry. Then discuss it with your specialist. This way we can all gather more useful info and try to find out what is hype and what is not.
There are two vitamins that currently interest me regarding malabsorptive patients. We all know the general fat solubles that we don’t fully absorb, Vitamins A, D, E, K. However as usual it’s not that simple.
Vit K for example has various forms. Like most of us I knew about bog standard Vit K1, the one we get from dark leafy greens and plant oils. What I never gave much thought to was Vit K2. I knew it is synthesized from Vit K1 to a degree , but that was about it. I stumbled on Vit K2 while I was driven to research how best to stabilize my bones and it has set me thinking.
A decent vitamin supplement should provide some K1 and K1 can synthesise to K2 in our intestines, but is it enough? Does it synthesize adequately to K2?
I’m not convinced. I am concerned about Vit K2 and whether we can produce enough of it. If ordinary people have deficiencies (see the first link below) then this is a real concern for WLS patients, surely? Vit K2 appears to play a vital role in our bone metabolism (more directly and more potently than Vit K1, it seems).
As usual I tried to find out more about the cons of Vit K2. And there are big cons (in both meanings of the word!)out there in the vitamin world, coral based calcium comes to mind
.
In any event, I could not find any medical papers that stated it had not worked during a trial. I could not find anything about potential side effects of overdose. If the link below stating that it is going to be added to milk in the USA is true, I presume it is indeed safe.( Idid I might add, have a temporary side effect but more about that below in my little tale of starting Vit K supplementation.)
Note: It should not be taken with anti-coagulant meds such as warfarin without consulting a GP first.
Also - I know Vit E can affect clotting of the blood but I have not yet researched how Vit K & Vit E interact.
Aside from benefits for the old bones, I would hope that the anti inflammatory role Vit K2 plays may also help DSers & RNYers who have gut/bowel problems. It may help UTI’s as well? Could lack of it play a part in Chrohns disease? Who knows. But it is all worth thinking about.
I also worry that the ‘clotting test’ commonly performed to check out Vit K levels is enough to know if we have a deficiency. It might not be (again based on the info in my first link below.)
There is a tendency among DSers to write off Vit E & Vit K as ‘lesser’ than Vit A & D…I fess up I was willing to see these as less important too - until I started researching it. I think we all need to know about Vitamin K2 as we may have several factors against us for it’s natural absorption and we might be highly deficient on account of our malabsorption:
- Firstly stomach removal might affect it’s absorption, in a cancer trial where stomachs had been partly or fully removed, the patients developed osteoporosis due to lack of Vit D…..if it is possible with Vit D is it also possible with K2?? ( I better quantify that this was full removal of the stomach - and we only get part removal. The study below was done on rats and is food for thought.
http://sciencelinks.jp/j-east/article/200403/000020040304A0026938.php
- Secondly our shortened intestines coupled with any bacterial overgrowth (even low grade) might very well inhibit our natural production of it. It is an intestinal bacteria.
- Thirdly, many of us have fat malabsorption to greater or lesser degrees. Like Vit K, Vit K2 is also fat soluble unfortunately.
- What about use of flagyl? Does it affect K2 levels? Should we supplement during or after flagyl use, even if we are not dealing with a bone challenge?
- Last, but not least I doubt (particularly as we malabsorb Vit K 1) that we can eat enough veg containing K1 to allow enough conversion of K2 in our intestines.
Studies show it has effect on both bone health and heart health & there is further speculation about it regarding liver cancer and other diseases. Obviously more research has to be done and hopefully it will be. It will be interesting to see if the osteoporosis drug companies don’t start releasing some ‘anti’ papers
!
Vitamin K is found in foods such as fermented cheese products, beef liver, chicken, butter and a fermented soya bean Japanese dish called natto - which I think I will skip as I hear it is slimy and smells of ammonia! Not for me!!! Cheese is going to be a better option for me - it seems cheese that undergoes fermentation is highest in Vit K2 - bring on the gouda! Cottage cheese also has it apparently. It might be a great option for RNYers and people who like it . I have found various foods listed that have it and yet these differ from source to source, so it’s difficult to be conclusive about it. As far as I know cottage cheese does not ferment, but even so, it’s good food for all surgery types. Try to verify VitK2 sources for yourself. While I will supplement with a natto based supplement as I have the bone thing going on and need to take a huge dose, I also will make a point of eating daily fermented cheese snacks to get it via food. Maybe liver & chicken will be more regular choices in my diet. As WLS patients we can’t go wrong doing this - we’ll get extra protein at the very least.
Q. How do you know if a cheese has been fermented?
A. Apparently any cheese that has holes in it has undergone fermentation.
My DS friends in the USA might be really pleased to see this: (Oh how I wish the UK would move faster on such issues!!! (Doing small frustrated muttering number!)

My little tale of starting on Vit K2:
I went to Boots and bought the Vit K2 a month ago. At night I lie wake fretting about the bone scans.. I actually don’t know how to do more calcium as the constipation already is gruelling.
A few DS surgeons are saying we must go for 4000mgs plus a day. But I wanna know (as usual), if we take this amount, and it is not being properly assimilated by the bones - where does it go? Is aIl the excess excreted via stool? What evidence is there that excessive calcium does not cause the body harm? I know it can circulate in the blood stream and make the labwork look a-okay when the reality might be that the bones are losing density. This is true of me. Apart from my last lab, all my other bone labs have come back looking good…but my bones…sigh.
Anyway I might try hedging the calcium figures up a little more despite my questions. I’m not looking forward to further constipation effects.
MenaQ7 (a brand of Vit K2) is not cheap - it’s another expense to consider. I had a lump in my throat not caused by over eating when I realised how much it would cost. I was so grateful for the 3 for two offer I nearly hugged the teller. I’m almost worried in a weird way, that it will work for my bones. How ironic is that. If it does - I’m worried that people won’t be able to afford it. It’s going to bite my budget hard, but I honestly feel it would be a waste not to take advantage of my dexa scans as fully as I can. And they will tell the tale for me about whether or not Vit K2 is as viable for malabsorptive patients as it seems to be for ‘normies’.
When I started K2 supplementation it felt like eating gold. But only for a short while. Firstly the pill is a hard little nut of a thing. I decided for best effect I would have to bite the casing. The taste is somewhat vile, but I can’t risk the pill does not dissolve. Next, I bloated up considerably and as nothing else had changed, I chalked it up to going into supplementation guns blazing. I researched but could find nothing about VitK2 related overdose. In fact nothing about overdose at all as it seems there are no side effects. 4 days into it and looking like a rotund Russian doll, I thought about chucking it in. Then I remembered my own good advice of the past : Start off slowly when introducing anything new! So I backed down on 150mgs and did 50mgs for several days, then 100mg and I am up to 150gms with no side effects currently.
A strange thing which I am freaking a little about is that I now have brown
poo that looks nearly like a normies number two. It still is stinky but it has a normie under current whiff which is also scary. At first I panicked as I thought I might be giving my malabsorption away. (And despite the extra vits, I treasure my malabsorption I truly do, as you all know.) But it still floats & smells mainly DSey, so I think it’s okay.
I’m thinking therefore that my luck might be in and that I am absorbing some K2. I truly hope so. Time will tell.

DEXA stuff:
I always believed in pref pre op Dexa scans for Bypass patients both RNY & DS. My own experience continues to convince me. For a long time my calcium blood labs tested as normal (not a surprise to me I might add as previous research I did shows this is common.) Only my most recent one shows a slightly low amount in my bloodstream. The last one 6mnths ago was normal. Meantime the dexa is confirming continuing bone loss.
What does surprise me is that my Vit D & PTH still look normal range despite the drop in blood level calcium, or maybe it is causing the drop, perhaps the calcium is actually being utilised! (Ever the optimist!). But hey - I am not complaining, Vit D & PTH normal is good news! Obviously despite my feelings about adding more undirected calcium into my diet and my constipation, I will do just that. But I don’t want the stuff circling around my blood stream being underutilized by my body.
With a history of genetic osteoporosis, I doubly feel a dexa must be done before a DS surgery as in my own experience, it may complicate the whole matter.
Add to this the fact that many WLS patients get WLS in their late 30’s and 40’s - and we are heading for menopause in our fifties, when bone loss often naturally accelerates. I don’t think we can underestimate a Dexa Scans role in giving us the best indication of bone health that technology affords us at this point in time, but just my opinion. Some medical people argue it as a requirement and point out some drawbacks, but what else is there? Blood labs can be even more uncertain and if I had only had blood labs, I’d not have known that my bones are losing density. (Sometimes I do think that ignorance is bliss, though probably not longerterm!)
Some patients do tell me that getting a dexa can be very difficult & some are outright refused the privledge. I don’t know if it might be of use but perhaps a visit to the dentist might help. (What!?, I hear you cry!
). I knew my bones were possibly losing mass before I had my first dexa.How? My dental x-rays showed minor bone loss in my jaws at the time. It’s not accurate and this is speculation on my part. Remember you can lose bone in isolation on your body, but it might be the only way to convince your GP that if you have bone loss in your mouth, you might have it elsewhere too. Besides you need to know the state of your teeth as these are sometimes affected by WLS too.
(BTW - another good reason to think on Vit K2 might be dental health. Think it was mentioned in one of the links below, or I read it somewhere. It might play a role in reducing gum disease. One thing in Africa that always struck me as amazing was the prevalence in rural areas of lovely straight strong white teeth, despite lack of dentists and technology. Now, by comparison just gander over the WLS forums where probs with teeth are sometimes discussed… Argh!!! I think too much!).
STRONTIUM:
During the course of my wading through piles and piles of potential misinformation and some more valuable info, I come across the fact that strontium is available in the UK on the NHS.
I found out that it does have side effects among them quite strong allergic reactions. Also that it needs to be considered with caution. Some feel that there is still a lot that needs to be learned about it. (See links below for various plus/minus opinions. ) But for now, I am still interested and think that although I am not yet confident about trying it (don’t want to feel like a lab rat yet ;-) erm, I forgot I already am one albeit a willing rat by proxy of my DS
), it’s worth keeping an eye on. The thing is we are not just talking about potentially stopping bone loss, it appears that strontium will also lay down new bone.
Only thing about the NHS source of strontium is it’s peppered with aspartamine. And wot’s the ranelate then? Mmmm. Reading the veritable side effects - it read a bit like the list of aspartamine toxicity to me. Reminds me of when deflatine decided to include sorbitol instead of sugar in it’s new formula. If you don’t know - sorbitol is sometimes associated with gastric distress!!! Where are their heads??? It’s probably all down to how cheaply they can manufacture something. Anyway if I decide to supplement with NHS strontium, I would have to accept the dayum aspartamine. I can’t afford not too unfortunately.
On the surface Vit K therapy looks less prone to side effects than strontium at this point in time. I think I will lay off strontium supplementation until I have had a consult with a bone specialist, but not by a long chalk am I closing the door on it. I have written about strontium here in the hope that others might know more about it, if so please e-mail me. (My e-mail contact is in the right hand sidebar.) Meanwhile I might just start munching more brazil nuts daily as they are apparently a natural source of it.
Stontium is also found in sea water but I think I will give this source a miss. (Yuck!)
Hopefully if K2 works & becomes more mainstream, it will be cheaper in years to come, or at least added to diary products world wide. Hopefully strontium will be as viable as I hope, but the jury is out on that one. For now I am organising my daily intakes of Calcium, magnesium, Vit D, zinc, VitK2 plus more, the best I can. Deep joy!

This is a debate about how excess calcium may affect our vascular systems. I’m open minded about it - but on reflecting the paper concerned I must say it didn’t wash well with me for several reasons, some of which the debate includes. I popped it here as I thought the one on Vit K2 and the snippet on magnesium were thought provoking.

SO WHAT ELSE MIGHT WE NEED FOR BONE HEALTH?
It was my DS friend Mellie who first pointed out to me, several years ago, the possible importance of adequate magnesium in bone metabolism disorders. She went on to develop a CalMagD supplement for us, which I take in conjuction with the calcium I get in V4L. ( The link is on the right side of this blog, first in the box.) As an aside, I have always questioned V4L’s formula of both iron & calcium in the same supplement. It might be neccesary for DS patients on V4L to bear in mind that down the line they may need additional calcium supplementation. (Keep watching your labs, get dexa’s if possible). If you are not taking magnesium ( check your vitamins -it’s sometimes included) discuss this with your specialist to work out beneficial ratio’s for your individual needs. Please read all the contra-indications in the below links too.
I’m learning magnesium also absorbs differently according to the type it is, not only that but it also has an elemental doasage. Currently I am on mag oxide (in the V4L) & mag citrate (in the CalMagD). I recently read the oxide is not great at doing it’s job. Citrate is a good middle road choice it seems. It’s actually supposed to have laxative properties, so maybe upping my dose might actually help my constipation. MMMmmm. I can but hope! Magnesium citrate might be a good choice for constipated WLSers then.

INULIN & OLIGOFRUCTOSE(FOS):
Interesting one this. I have always felt intuitively that trying to supplement on a gut that is not in fundamentally good health may hinder nutrient absorption. Note that initially inulin supplements might cause temporary bloating.
Foods high in inulin: dandelion, chicory, onions, artichokes, bananas, asparagus, garlic, leeks.

LUTIEN:
This is not connected to Bone metabolism, but thought I would mention it here anyway as I think it’s an important one.The other nutrient (that possibly no one told you about) is Lutien. This plays a role in vision & eye health.
Yup, I supplement this too. Have done for quite a while. I will blog more about it in my following blog which will start with Vitamin A.
I thought I would compile a list of important Vitamins and try to top up my own knowledge again. Got to do it as part of updating my website anyway, knowledge about them moves on. So, if you are interested, keep ploughing through my ever voluminous blogs!
As usual, please note that you should consider consulting with your surgeon when introducing higher or lower doses of vitamins, or if introducing new vitamins as you may be on other meds that could be affected by supplementation or have different health issues than me.
