Hi there Redwind,
First of alll, you need some perspective here. You have been diagnosed with OP (with a scan?) and are now on meds. plus vitamins and calcium to protect your bones and to significantly reduce the risk of any fractures. Now, no one likes to be diagnosed with ANY illness but, as ilnesses go, it could be a lot worse. You can live a normal life but should just be a little more careful of things like heavy lifting, doing movements which involve bending forwards (like touching your toes), and especially try to avoid slips and falls. Not too hard eh? A wise woman should probably do this anyway.
OP is a hugely common condition - it is estimated that 50% of woman over 50 will have a fracture due to undiagnosed OP. The first manifestation of it is usually a fracture and then a shrewd GP may suggest a bone scan which shows up OP. There are a variety of medication used to treat it and your doctor has selected one for you. If this doesn't suit you there are others. Aslo as others have said, you need to exercise as well as your Calcium and VitD. The best exercises are weight-bearing ones (walking, stair-climbing, dancing). Swimming and cycling, though great exercises, will not help your bones. Now, if you never had OP, you should be doing some form of regular exercise anyway, so my tip would be - find something you enjoy and do it regularly but not obsessively! By the way, athletes can get OP, dancers, those with dietary conditions, children and those who may be taking various medications for cother conditions - all ages. it's not just older adults.
Re. your little dog. I'm so sorry to hear about loosiing him. This forum must be full of dog lovers, judging by the post you've already got about them. The advice you got here is great - GET ANOTHER DOG (when you're ready) I've had small dogs for decades (Yorkies) and couldn't imagine living without them. One of my little treasures had to be put to sleep last Feb. and I'm still not over it. Only another dog lover understands this. Others think that it's" just a dog", but it's not. It's a little being who has shared your life and who has given you so much love and companionship. And it's heartbreaking when whey go. But there is NO REASON WHATSOEVER why you shouldn't get another. You would be a huge bonus for the dog. And he'd be part of the 'new you' who is getting her act together and starting out on a healthier life - with Rover's help!! A suggestion here, however, I wouldn't go for a huge thing who needs 10-mile walks each day, who eats like a horse and who might run away with you!!
Final piece of advice, I don't know where you live but if you have an OP society, check in with them, they would have loads of helpful information. Ask them if they could suggest someone your age who you could call if you needed.It could be a great comfort. They may also have a helpline, staffed by an OP nurse who will answer any of your questions - even the most daft ones - the've heard it all!!
You'll also get support from this forum. So keep in touch.
Very kind thoughts. Do take care of yourself - you're so worth it.
