Post-dural puncture headache (PDPH) is most commonly seen in certain groups of patients due to various factors such as age, anatomy, and physiological characteristics.

1. Elderly: While the elderly population might have variations in their anatomical and tissue properties, the incidence of PDPH does not significantly distinguish them as the most affected group.

2. Morbidly Obese: Obesity may complicate spine access and some anesthetic techniques, but it doesn’t necessarily correlate with a higher incidence of PDPH.

3. Male Sex: Research shows that males do not experience PDPH at a higher frequency compared to females.

4. Female Sex: Studies indicate that females are at a greater risk for developing PDPH compared to males, likely due to hormonal differences and anatomical considerations.

5. Diabetics: Diabetics may have other complications and risk factors, but they are not specifically more prone to PDPH compared to the general population.

Thus, based on the available data, female sex is considered the group most commonly affected by post-dural puncture headaches, making them the most at risk in clinical settings.
