High blood pressure symptoms, signs and risks. High blood pressure, or hypertension, doesnât usually cause any obvious symptoms. The British Heart Foundation estimates that up to 5 million people in the UK have undiagnosed high blood pressure. Left untreated, hypertension can lead to serious diseases, including stroke, heart disease, kidney failure and eye problems.
Ringneck Snake (Diadophis punctatus) Description: Ringneck snakes are small -- 10 - 15 in (25 - 38 cm) -- slender snakes that are generally grayish with a yellow or orange band around the back of the neck and a yellow or orange underside. Two subspecies are found in our region.
The northern ringneck snake (Diadophis punctatus edwardsi) inhabits the mountains and generally has a complete neck ring and unpatterned underside. The southern ringneck (D. p. punctatus) is found in the Coastal Plain and often has a broken neck ring and underside that is marked with a single row or black spots.
