What is Ankylosing Spondylitis?
Ankylosing Spondylitis (or AS) is an inflammatory arthritis that affects the joints. Primarily the spine and pelvis, but it can also affect other joints, such as the wrists and ankles, and in rare instances organs such as the heart, lungs, and intestines. Most cases typically present with bouts of pain and stiffness followed by periods of remission.
What causes AS?
There is no definitive cause of AS. There has been a genetic link found in recent years with the gene HLA-B27. As the disease progresses, new bone forms at areas of inflammation in an attempt to heal the area causing fusion of joints.
Onset is usually in young adulthood between the ages of 17-45. It is more common in men, and those with a family history of the disease as there is a genetic link.
Is there a cure?
AS is a chronic, degenerative disease that currently has no cure. Western Medicine treatment typically involved the continuous use of NSAIDS (non-steroidal anti-inflammatory drugs). Catching the disease early is very important for treatment. With proper diet, exercise and in some cases physical therapy, the disease can be managed.
Diet: Eating a low inflammatory diet is very important. You can undergo a blood test that will help you identify any food allergies you may have. Food allergies can be unexpressed, or mild in symptoms and you may not have a anaphylactic reaction to them. So, testing is an important step. There are also certain foods that can create inflammation in the body and should be avoided.
Exercise: The goal when exercising as therapy for AS, is the maintain posture and joint flexibility. Exercises such as Yoga can help avoid complications with curvature of the spine, and can help keep joints open.
Surgery: In extreme cases surgery may the last option in the form of joint replacements,, or correction of spinal curvature. Surgery is risky and should be used as a last resort.
So, where does Acupuncture fit into the picture?
Other therapies such as Massage, Tui-Na, Acupuncture, Moxibution and Electro-Acupuncture can offer relief from pain, and decrease inflammation in the body.
A meta-analysis published in the Archives of Internal Medicine concluded that, "Acupuncture is effective for the treatment of chronic pain and is therefore a reasonable referral option."
When we are treating a client with Acupuncture for inflammatory arthritic conditions such as AS, we are treating the body as a whole. We are treating any imbalanced that may be attributing to bouts of inflammation and we are treating acute flare ups with Acupuncture Needles, Electro-Acupuncture and Moxibustion. All of these have different effects on the body.
Acupuncture: depending on the presentation points will be selected that balance the immune system response, reduce inflammation and easy pain. Acupuncture causes neuropeptide release from nerve endings which subsequently have vasodilative and anti-inflammatory effects through the calcitonin gene-related peptide. 
Electro-Acupuncture TENS: Electro-Acupuncture significantly increases the plasma levels of natural corticosterone, and suppresses inflammation by activating the hypothalamus-pituitary-adrenal axis (HPA) and the nervous system.5]
Moxibustion: With Arthritis moxibustion at BL 23 can lighten local inflammation, eliminate swelling, prevent and/or reduce polyarthritises. It can help with recovery and promote the effects of concanavalin, inducing splenic lymphocyte proliferation

Vitamin D deficiency can be characterized by the following symptoms; general bone pain or muscle pain and weakness; muscle cramping; unexplained depression; fatigue; lack of concentration; mood swings; anovulation; low sperm motility; childhood asthma; sleep irregularities. Unchecked Vitamin D deficiency can lead to severe conditions involving the Cardiovascular, Musculoskeletal, and Neurological systems. If you are experiencing any of the above symptoms as well as infertility, you may have a level of Vitamin D deficiency.
There are many underlying causes associated with infertility, but there is one nutritional concern that seems to be popping up more frequently, Vitamin D deficiency. The common occurrence of Vitamin D deficiency, “the sunshine vitamin”, is a hot topic right now. The debate rages as to why so many people are testing low for this essential vitamin, 90% of which comes from our exposure to sunlight.
Vitamin D is a pro-hormone vitamin, meaning it is necessary in the production of reproductive hormones in both men and women. Vitamin D receptors have been found on male testes and sperm, the ovaries of women, and placenta. The research on how Vitamin D affects fertility is limited, but what they have found so far seems very promising. There have been several studies linking Vitamin and Polycystic Ovarian Syndrome, which is one of the most common causes of anovulation in women.
One such study, from the Yale University School of Medicine, concluded that of the women testes only 7% had normal Vitamin D levels. 
Dr. Lubna Pal, from Yale, said: "Of note, not a single patient with either ovulatory disturbance or polycystic ovary syndrome demonstrated normal Vitamin D levels; 39 per cent of those with ovulatory disturbance and 38 per cent of those with PCOS had serum 25OHD levels consistent with deficiency.
Another study found that Vitamin D worked as a modulator for implantation of the fertilized egg and formation of the placenta.  Which if deficient, could lead to miscarriage.
Researchers from Denmark found an increase in sperm motility when men with low sperm motility were given Vitamin D supplementation. 
So, how much Vitamin D do you need? Well, that varies depending on your age, skin type and underlying health conditions. The body can make between 10,000-20,000IU from sun exposure alone. Often those suffering from deficiencies will need to take high doses of vitamin D to alleviate their symptoms, but it is always best to consult a professional before taking any vitamin supplements.
