I AM under pressure at work and finding it difficult to go to sleep.

I keep thinking about what needs to be done the next day, then worry about how tired I am going to be.

l Insomnia is a common symptom of stress.

There are various things you can do to help you manage your stress.

Eating healthily, exercising and making sure you wind down before going to bed can all help. Avoid caffeine and alcohol in the evening as these can interfere with sleep.

If you have work worries it is important to talk about your feelings with those who care about you.

It would also be worth considering a discussion with your line manager at work if you are facing unreasonable demands.

If you prefer to speak to someone you don't know, call Breathing Space on 0800 83 85 87 to talk in confidence with trained advisers. Lines are open 6pm Friday to 6am Monday and from 6pm to 2am Monday to Thursday.

If you are still having problems sleeping, discuss it with your GP.

HOW many caesarean sections can you have?

l There is no limit to the number of caesarean sections you can have.

However, the risk of complications during pregnancy and birth is higher if you have had one or more caesarean sections before, because having a caesarean section produces a scar on your womb where the incision is made.

Having had one or more caesarean sections can also slightly increase the risk of complications for your baby in later pregnancies. For example, the risk of stillbirth is two in 1000 for women who have never had a caesarean section compared to four in 1000 for women who have.

However this is still a very small risk.

When you are due to give birth, your doctor will take account of your preferences, the risk and benefits of caesarean section or vaginal birth, and the risks to you and your baby's health.

The medical reasons for having a caesarean far outweigh potential risks to future pregnancies, or to the health of you and your baby.

LOW blood pressure - also sometimes referred to as hypotension - is a condition where the arterial blood pressure is abnormally low.

On its own, hypotension does not always cause symptoms. If you have low blood pressure but no symptoms, you do not need treatment. However, low blood pressure can sometimes mean there is not enough blood flowing to your brain and other organs, and you may experience dizziness, fainting, light-headedness, blurred vision, nausea, palpitations, confusion or weakness.

Increasing your fluid and salt intake can help but if medication is necessary, it will usually expand the volume of your blood or constrict your arteries, increasing blood pressure.
