3. Unexplained Weight Loss – A Subtle Sign of AAA
Unexplained weight loss can be a subtle sign of a serious medical condition, including abdominal aortic aneurysm (AAA). AAA is a ballooning or weakening of the aorta, the main blood vessel that carries blood from the heart to the rest of the body. If left untreated, AAA can rupture and lead to life-threatening internal bleeding.
While AAA can present with no symptoms at all, some people may experience a persistent abdominal or back pain, or a pulsating feeling in the abdomen. Unexplained weight loss can also be a sign of AAA, as the aneurysm may cause changes in appetite, digestion, and metabolism. In some cases, weight loss may be accompanied by fatigue, weakness, and a loss of energy.
AAA is most commonly diagnosed in people over 60 years of age, and is more common in men than in women. Risk factors for AAA include smoking, high blood pressure, family history of aneurysms, and atherosclerosis (hardening of the arteries).
Diagnosis of AAA is usually made through imaging tests, such as ultrasound, CT scan, or MRI. These tests can show the size and location of the aneurysm, and can help determine the best course of treatment. In some cases, a more invasive test, such as angiography, may be necessary to get a more detailed view of the aneurysm.
If an AAA is detected, treatment options may include close monitoring, medication to control blood pressure and reduce the risk of aneurysm rupture, or surgery to repair the aneurysm. The choice of treatment will depend on the size and location of the aneurysm, as well as the overall health of the patient.
Surgery to repair an AAA involves either an open repair, in which a large incision is made in the abdomen, or an endovascular repair, in which a small incision is made in the groin and a stent-graft is inserted into the aneurysm to reinforce the weakened area. Both types of surgery have their own risks and benefits, and the best choice of surgery will depend on the individual patient’s situation.
Although weight loss can be attributed to many factors, such as stress, changes in diet, or an underlying medical condition, it should never be overlooked. If you experience unexplained weight loss along with other AAA symptoms, consult your healthcare provider for a thorough evaluation. Early detection and treatment can significantly reduce the risk of aortic rupture and associated complications. (3)
