**Latest**: Yellow fever vaccination
Pencoed Medical Centre is now an officially registered
"Yellow fever centre". This means that anyone requiring yellow fever vaccination
(required when travelling to certain parts of the world) - whether they are a
patient of ours or not - can receive all of their necessary vaccinations at
Pencoed Medical Centre.
One of the benefits of the Internet is that it can be accessed from all over the world. At the Medical Centres, we are often asked questions about travel and disease whilst abroad on holiday. This page includes some of the more common queries. We are aware that patients may find themselves ill whilst on holiday and this page is designed to give our patients general advice that they may access whilst away from home. It is NOT intended to replace a proper consultation with a Doctor. If you are worried, please seek proper medical advice as you would if you were at home. If you have visited this page, please let us know - we would be delighted to hear any suggestions on improving this section and to know if you found it useful. We will add to this page depending on feedback from our patients. Unfortunately, we are unable to respond to e-mail enquiries of a personal nature for medico legal and security reasons (as outlined on our homepage).

Sunburn
First of all, try not to get sunburn at all! Prevention is
all important in the case of sunburn. There is clear evidence that sun exposure
can increase the chance of developing cancerous lesions, including "Malignant
Melanoma". This may be even more important when children become sunburnt.
| Avoid going out in the midday sun | |
| Use a high protection factor (30+) sun screen, applied thickly and re-applied regularly. Pay particular attention to the tops of the ears, "mask" area of face, nose, shoulders. Re-apply if going into water etc. Remember sunblock for lips and glasses for eyes. | |
| Cover up with a hat and clothing - bear in mind that a thin shirt may not provide full protection and you may still need to cover completely with sun screen. Children and babies are at a particular risk. | |
| Keep in the shade - but remember that you may still burn - including on cloudy days! | |
| Drink plenty of fluids. Water is best. Avoid alcohol, because it is a diuretic. This means that alcohol will stimulate your kidneys to produce urine - so you may lose more water from the body if you drink alcohol (it's not a very good way of rehydrating yourself!). If you drink alcohol, remember to drink plenty of water to overcome the diuretic effect. |
If you already have sunburn, then there are a few thing you can do to make yourself comfortable.
| Drink lots of water to rehydrate | |
| Calamine lotion can be soothing when applied to the skin. An antihistamine cream may help. | |
| Because the skin's surface is red and the fine vessels in the skin are dilated, there may be several consequences. First you may evaporate fluid (this is why you need fluids) and second, you could lose your body heat and become very cold. | |
| Remember that, if severe, sunburn can actually be very dangerous - particularly in the elderly and very young. If the patient becomes very drowsy or listless or your own common sense tells you that they are very unwell, then do not hesitate to see a Doctor. |
Diarrhoea
Diarrhoea means passing frequent loose, watery stools.
Most cases of diarrhoea are due to infectious causes. In other words, you may
have taken bacteria or viruses by mouth (from dirty hands, food or drink).
Prevention is better - bottled "safe" water for drinking, washing food and
brushing teeth, hand washing and clean all vegetables & fruit (bearing in mind
the safety of the water used to clean the food!). Our bodies may try to get rid
of these bugs by trying to eradicate them from the bowel as quickly as possible.
This may lead to vomiting and diarrhoea. The most important thing here is to
replace fluids. Drink as much as you can - "little & often" if you cannot
tolerate large volumes. In addition to fluids, you may lose essential salts from
the body. It is possible to replace fluids and salts by drinking special
rehydration drinks - "Dioralyte" and "Electrolade" are two examples. These may
be purchased from the chemist before you go (or they may be available abroad. If
not, the local pharmacist may be able to offer a similar product). Don't worry
if you cannot tolerate food. In the short term, fluids are much more important.
It may be best to avoid dairy products, because some diarrhoeal illnesses can
temporarily affect our ability to digest "lactose", which is a sugar found in
dairy products. If you are lucky, you may be able to flush out the bugs by
taking lots of fluids by mouth. Sometimes, this is not possible and some
infections may need specific treatment - again, if you are concerned, the
diarrhoea is prolonged (72hrs in a fit adult, but as little as 24hrs in the
elderly or child), or the patient is listless and drowsy, feverish, blood in the
diarrhoea, then do not hesitate to see a Doctor (as you would if you were at
home). Finally, a word on constipating agent such as "kaolin & morphine" etc.
Some products sold over the counter have the effect of "stopping" or slowing
down the diarrhoea. Although controversial, this may impair your body's attempts
to "flush out" the bugs. If the cause is an infectious diarrhoea, you may be
better avoiding these products and drinking as much as you can. Again, children
(& babies) and the elderly can be particularly susceptible to diarrhoea - have a
low threshold for seeing a Doctor if you are at all concerned.
Deep Vein
Thrombosis (or "DVT", "Economy class syndrome")
A deep vein thrombosis is due to a blood clot in a vein.
"Economy class syndrome" is a misnomer - the problem is not restricted to
economy class, nor flying in general. Thrombosis can occur anywhere in the body,
but clots in the deep veins of the calf muscle (below the knee at the back of
the leg) are what are termed "DVT". The classical symptoms are those of swelling
in one leg (if you press hard with a finger, it will leave a dimple when
the finger is removed), pain, redness and heat in the muscle. A DVT in one leg
will not produce symptoms in the other leg - so, DVT usually leads to symptoms
in one leg rather than both (unless, by chance you have contracted
DVTs in both legs at the same time). In other words, one leg appears more
swollen that the other. Often, the calf muscle may also feel hard. Sometimes
dorsiflexing the foot (the same movement that you make with your ankle if you
were lifting your foot off the accelerator of your car) may produce pain in the
calf. A DVT may present with some, all or none of these symptoms. Other
conditions may produce similar symptoms (muscle strains, skin infections and
rupture of cysts behind the knee). A DVT can be fatal. If you are concerned that
you may have a DVT you should see a Doctor immediately. The following can
be risk factors for developing a DVT:-
| Dehydration, Immobility, Pregnancy & "the pill", Cardiovascular disease (including stroke) | |
| Malignancy, Recent major surgery, low oxygen pressure in aircraft, tight restrictive clothing. |
There are a number of things that you can do to reduce your chances of getting a DVT
| Exercise your calf muscles regularly. DVTs occur more often when people are immobile (sitting around, on a long plane, bus, car or coach journey). Either get up and walk at regular intervals or exercise your calf muscles (as if alternately pressing the brake and accelerator pedals of a car repeatedly with both feet) at regular intervals. | |
| Dehydration increases the risk. Drink lots of water. Alcohol may stimulate urination, so it's not a good way of rehydrating yourself. Water and non-alcoholic drinks are best. Remember that "diuretics" or "water tablets" may lead to loss of fluid from the body. People become dehydrated quicker in hotter climates. | |
| Wearing specially produced compression stockings may help. | |
| Aspirin (provided there are no medical reasons why you should not take it) may help. There is debate as to what is the ideal dose. People who have (or have had) stomach ulcers or asthmatics (to name only a few conditions) may not be able to take Aspirin. | |
| Some people are more prone to developing thrombosis. Obviously, if there is a family history, you may be at a higher risk. Oestrogen hormones may increase the risk. Since oestrogens are found in the "Combined" oral contraceptive pill, this may increase your risk. There are no oestrogens in the "Mini (progesterone only) pill". DVT tends to be a disease that affects adults and more so as people get older. The author of this article has never heard of a DVT occurring spontaneously in a child. However, if you are concerned about DVT in any age group, see a Doctor immediately. |
NHS Direct have produced a section on DVT Click here to learn more (remember that we are not responsible for the content at external sites)
A House of Lords Select Committee carried out a comprehensive review of the subject in November 2000. They concluded that the risk of developing DVT following a long distance flight is estimated to be between 0.1 and 0.4 per thousand of the general population.
Travel and
Pregnancy
You should not travel abroad whilst pregnant if you have a
history of miscarriage, premature labour, vaginal bleeding in pregnancy or "pre-eclampsia"
(a condition where blood pressure goes up to dangerous levels). Airlines are
generally reluctant to accept a woman who is more than 32 weeks pregnant - check
with your individual airline (and check that you have a seat with enough room!).
You will be at an increased risk of DVT (see above). You should carry
comprehensive documentation including estimated date of delivery and blood type.
Check that you have valid travel health insurance covering duration of the
pregnancy, complications, delivery and the postpartum (i.e. after delivery)
period. Also check that this policy covers the newborn and that repatriation is
available and covered, if necessary. If travelling to an endemic area, the risk
of malaria is significant and potentially very serious for both mother and baby
during pregnancy. You must weigh up the risk/benefit of antimalarial medication,
but Chloroquine and Proguanil have been prescribed safely in pregnancy for many
years (your Doctor may recommend taking Folic acid 5mg on alternate days if you
are taking Proguanil). Generally speaking, "live" vaccines should be avoided in
pregnancy but "inactivated" vaccines (such as Hepatitis A, Typhoid and Tetanus)
may be given safely, preferably during the second and third trimester of
pregnancy if there is a significant risk of contracting these illnesses.
Remember that the illnesses themselves may be more dangerous to you and your
baby than the risks of any medication.
The Diabetic
Traveller
Any illness contracted will pose a greater threat to
diabetics, whether diarrhoea, infections, malaria or seemingly minor illness.
You should be especially careful to prevent any illnesses. In particular,
you should be up to date with all of your immunisations and you should have a
very low threshold for seeing a Doctor if you become unwell. Make sure that you
have adequate supplies of needles, syringes and insulin in your hand luggage.
Blood sugar testing machines (and spare batteries!) are a good idea. Insulin may
remain stable at room temperature for one month, but it may be destroyed by
freezing (as can happen in the cargo hold of an aeroplane). Unaccustomed
exercise in a different climate (or unexpected delays) may make your blood sugar
drop quicker than it does at home, so you should always carry a supply of
carbohydrate to stave off hypoglycaemic attacks. If your journey lasts less than
8 hours, you may wish to stick to your home time management of your diabetes.
For long journeys, work out changes to your insulin regime well in advance by
consulting diabetic clinic. Make sure that you have comprehensive travel health
insurance that covers diabetic patients.
Pre-existing
illness
If you have had a heart attack
(myocardial infarction) you should not fly within two to four weeks, depending
on severity. A patient who has had ear surgery should not fly
within two months. If you have a perforated eardrum, you should
wait until it has healed completely before flying. Surgery
involving a body cavity (such as chest or abdomen) or pneumothorax ("collapsed
lung") should not travel for at least three weeks. If you have
chronic obstructive airways disease or emphysemia, you
may need supplementary oxygen during the flight and you should discuss the
matter in detail with the airline and your Doctor beforehand. Patients treated
for cancer with chemotherapy or radiotherapy
should not have "live" vaccines until 6 months after the end of treatment. Of
course, all of this advice is very general and you should discuss your
exact individual requirements with your own Doctor well in advance of making
plans to travel. Make sure that you have comprehensive travel health insurance
and that it covers all pre-existing conditions.
Minor cuts and
grazes
Our skin provides defence against the bugs that lead to
infection. A cut or graze may allow bugs in. If the wound is bleeding, apply
pressure for as long as it takes to stop. This may be as long as 15 minutes. If
the bleeding continues, continue to apply pressure. Bleeding from points below
the heart can be greater, so you can help to reduce the bleeding by lifting the
affected limb above the level of the heart at the same time. Next, clean the
wound using an antiseptic solution (salt water if none available) and apply a
clean dressing to prevent contamination with bugs. You may need to consider
other risks, such as HIV and Hepatitis B, if applicable. Tetanus is a risk, if
you have not been immunised or not had a booster within 10yrs. If the wound gets
more painful, or surrounded with an increasing area of "redness" and swelling,
or if it discharges coloured pustular fluid as the days go by, this could be a
sign of infection. If infection develops, you should see a Doctor because you
might need antibiotics. Again, see a Doctor if you are at all concerned.
Insect bites
Insect bites usually produce multiple itchy bumps a few
millimetres in diameter. You may ease the symptoms by using an antihistamine
cream or tablets. Common antihistamines are "Piriton" (chlorpheniramine), "Clarityn"
(Loratadine) and "Zirtek" (Cetrizine). Be careful if you are driving - some
medicines may make you feel drowsy.
Hayfever
An allergy to pollens - can include tree pollens as well
as grasses and flowers. Tree pollen allergy can occur early (March) in the year.
Symptoms include itchy, watering eyes, nose and a cough. Mainstay of treatment
is with antihistamines (see above) in the form of eyedrops, nasal spray and/or
tablets. Generally speaking, tablets tend to be more potent and have a
widespread action. It is also possible to use a steroid spray e.g "Beconase" (Beclomethasone),
but this may take several days to achieve full effect (up to 14 days or longer).
These treatments are available over the counter at the Chemist. Be careful if
you are driving - some medicines may make you feel drowsy.
Travel sickness
Treatment is usually with an anti-emetic pill (e.g. "Stemetil").
Some may have a sedative effect. Be aware, if you are driving, that this
treatment might make you feel drowsy. Eating "little and often" may be better
than large, fatty meals.

See notes under our other health information pages. Remember R.I.C.E. - Rest, Ice, Compression with a bandage or "tubigrip" and Elevation of the limb. If the patient is unable to move the limb, weight bear or if there is obvious deformity, then there could be a broken bone.
Women's health
You may find our pages on
"The Pill" useful. It is possible to postpone your
menstrual period by taking tablets ("Norethisterone" 5mg three times a day
starting 3 days before anticipated onset of menstruation. Menstruation occurs
2-3 days after stopping the tablets), but you would need to discuss this in
detail with your Doctor beforehand and you would need a prescription, provided
that this medicine is suitable for you.
Holidays in
the UK
Remember that you have access to an NHS GP wherever you
are in the UK. Simply contact the nearest GP (even if you need a Doctor out of
hours) and he may look after you as a "Temporary Resident". If you have
unexpectedly run out of tablets, you may be able to get an emergency supply from
the chemist if you take the empty packets and identification along with you.
Medicines
Obviously, remember to take plenty of medicine with you,
taking into account possible delays. Remember that the cargo hold of the plane
may be cold enough to have a detrimental effect on your medicine - including
insulin for diabetics. It may be better to keep your medicine in your hand
luggage and keep it with you at all times. Paracetamol is very, very useful if
you need it - particularly if you have children! You may wish to take a supply
of "Calpol" (paracetamol) with you "just in case".
