Researchers studying the effects of acupuncture for chronic prostatitis/chronic pelvic pain syndrome, randomised 89 patients into two groups, receiving either true or sham acupuncture, twice-weekly over ten weeks. (The sham group acted as a control and were lead to believe they were experiencing real acupuncture.) In the true acupuncture group, 73% of patients responded, compared to only 47% in the sham group. At follow-up 24 weeks later, this level of response was maintained by 32% of the acupuncture group and only 13% of the sham control group. Patients receiving true acupuncture were thus 2.4 times more likely to experience long-term benefit.

Heartburn, caused by reflux of stomach acid, is a common symptom, and may be due to simple indigestion or due to a condition such as hiatus hernia. Proton pump inhibitor drugs, such as omeprazole, are often prescribed to control it, and if they are not working, standard practice is to double the dose.
An American clinical trial looked at acupuncture for heartburn and enrolled thirty patients who did not respond to the standard drug dose. They were randomly assigned to receive either double the dose, or standard dose plus two acupuncture sessions per week. After four weeks, the acupuncture group demonstrated a significant decrease in heartburn day and night, and in acid regurgitation. The double drug dose group did not demonstrate a significant change.
The authors noted that acupuncture was found to enhance gastric peristalsis, as observed by ultrasonography, and to accelerate gastric emptying in dyspeptic patients with documented delayed gastric emptying.

This trial investigated the effects of acupuncture for high blood pressure, and in particular as an add-on to conventional hypertension management eg. medication and lifestyle measures. Forty-one volunteers were allocated randomly to receive either acupuncture or sham acupuncture; the latter is where the patient is touched in a way that leads them to believe a needle has been inserted, when it has in fact not. Those patients already on medication, continued to take it. After eight weeks, the sham group showed no significant change in blood pressure, whereas the acupuncture group showed a significant decrease, from an average 136.8/83.7 to 122.1/76.8 mmHg.
