How does pregnancy increase the risk of pulmonary and other emboli?

---

How is pregnancy associated with an increased risk in pulmonary embolism? Does this explain the association between long term use of oral contraceptives and thrombosis, which could possibly lead to embolism?
Yes and no. The hormones that are increased in pregnancy and contained in the contraceptive Pill aren't the only risk factors for blot clots forming during pregnancy. What the Pill and pregnancy both have in common is that they both produce hormones that increase the bloods clotting ability. Oestrogen increases the risk of DVTs by increasing the production of certain chemicals necessary for the blood to clot. It also increases platelet numbers + stickiness of platelets, which increases clot formation (to prepare for blood loss during child birth). Progestogen in the Pill causes the blood vessels to relax and widen, allowing the blood to pool in the veins, increasing risk of clot formation.

Blood clots in pregnancy are generally the result of increased venous stasis- blood pooling in the lower deep veins. As I said above, balance of proteins of the coagulation + fibrinolytic systems also play a part. DVT can of course lead to a pulmonary embolism. Clots in pregnancy and from the Pill are generally always the results of clots that have formed in the deep veins of the legs, broken away and then embolised in the lungs.

Women who do have clots in pregnancy and whilst taking the contraceptive Pill, generally also have certain other risk factors such as protein C and S deficiency and most commonly Factor V Leiden mutation. Over all health of the woman also plays a part- obesity, poor diet/unhealthy lifestyle and a smoking history also increases the risk as does age.

During pregnancy the uterus also expands, putting pressure on the lower blood vessels which can restrict blood flow from the legs and pelvis back to the heart. Physiological structural changes during pregnancy are risk factors alone.  (+ info)

What are the chances of my baby getting pyloric stenosis?

---

My second son was born with pyloric stenosis, it was corrected when he was 4 weeks old. He has had several problems since, has gastral reflux disease and his bowels are not working. They are looking into him having chrons disease and he is only 3?
What are the chances of this baby that I am pregnant with having the same issues?
sadly if its a boy the chances are pretty high, but only your doctor would know that for sure, almost all the boys in my family has some form of intestinal illness and/or chrones, some of the girls also have it but it is not as common, if its a girl then the chances are slimmer that she would have these problems but not impossible, talk to your doctor about this and they should be able to advice you better than anyone on here

i hope all does well and so sorry to hear about your sons suffering, my son was premature and is in the same boat as your son also, my son is only 22months old  (+ info)

Is having a cervical spinal stenosis can be a valid reason to apply and won for SSS disability?

---

I had an MRI and it said that i have a moderate to severe cervical stenosis.
If you are under 50 or 55 it would be very difficult to win a disability case for this. If you are over 55, haven't worked in the last 15 years and haven't completed high school, you would qualify.  (+ info)

What are the multidisciplinary team responsibilities for the patient suffering a pulmonary contusion?

---

I have a case scenario which I am writing an assignment on. (Pulmonary contusion and Acute Respiratory Failure) part of this assignment requires me to discuss the multidisciplinary roles. The info on this is not very clear, I recognise there are roles played by the physiotherapist and nurse also the physician and have a general idea of what they are but need confirmation, Can anyone help?
let the nurses do everythng, cause they are the know-it-alls of the medical field.  (+ info)

What is unique about blood in pulmonary arteries compared with blood in other arteries?

---

a. It is loaded with carbon dioxide.
b. It is moving toward the heart.
c. Blood in pulmonary arteries is always blue; it is red in all other arteries.
d. It is the same as blood in other arteries.
e. It is moving away from the heart.
A and C...but if you had to choose go with A  (+ info)

My sister has been diagnosed with Congenital Spinal Stenosis, what is the likelyhood of me having it?

What is the average lifespan of someone with Aortic Stenosis?

---

I'm 19 and was born with congenital aortic stenosis the symptoms are just moderate/serious at the moment. I just wanted to know what is my average life span, say with out any medication or operations?
I'm not worried, I'm just interested.
Well I am sort of worried it gets me down because it's really painful. :P
I dunno life expectancy, whatever?
Nobody thinks of untreated life span these days. Good treatment is available. Some do well with just medications, others with balloon valvotomy or valve replacements. Anyway, with modern treatment, life span of a person with congenital aortic stenosis is pretty long for you to stop worrrying!  (+ info)

What is the difference between asbestosis and pulmonary fibrosis?

---

My husband has been advised by his consultant to claim industrial disease allowance for his pulmonary fibrosis.Has he worked in shipbuilding with asbestos we expected to be told he had asbestosis!Should we be pleased or is it two names for same illness? He has lost a lot of former colleagues to asbestosis and so we and especially me, are very concerned about his quality of life in the near future.
asbestosis is caused by exposure to asbestos asbestos fibres are thin and microscopic and easily pass through the filters in the nose and bronchi into the lungs it sticks to the lungs and scars the lung tissue it makes it harder for the lungs to function properly and gas exchange gas exchange in the lungs gets harder it can cause respiratory failure and can take years to develop
pulmonary fibrosis scars the tissue in the lungs eventually the air sacs in the lungs are all replaced by fibre or scar tissue this tissue is thicker and the tissuyes cant transfer oxygen to the blood anymore  (+ info)

What is bilateral pulmonary disease and what causes it?

---

Recently a friend became ill and everyone including her felt it may be flu as it is flu season. But, she complained of shortness of breath and had to be given oxygen. Later she had the problem again and had to be given oxygen. It is said that she had a bag full of fluid removed from around her heart and mucus started to solidify in her lungs.Diagnosis was bilateral pulmonary disease which few people have heard about or understand except that it affected her breathing. What causes such a disease? Could the aircondition in an office be a factor?

When is it safe to travel after a pulmonary embolism?

---

A friend visiting from Europe developed a pulmonary embolism after a surgery. She has been started on a blood thinner. When is it safe for her to fly back home?
Never. She needs to become an American citizen and stay here forever. Or at least take a boat home and not a plane. LOL  (+ info)
