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 grass snake grows larger than the adder and a specimen I found near Speech House in the Forest of Dean measured 120cm, if this snake is still alive today it could be over 4 foot long, but even this is small compared to some that can reach 200cm or more!
