It is important to prepare your trip well in advance. Follow these general guidelines before getting ready to travel.
A Deep Vein Thrombosis (DVT) is a clotting of the blood in any of the deep veins – usually in the calf. If a clot develops, you will feel an intense pain in the affected calf. You should seek medical attention immediately if this occurs, especially after a long journey.
A DVT can occur some days or even weeks after a trip. In most situations you may not have any symptoms.
If the clot is large it can cause an obstruction and prevent the blood flowing through the veins. When this happens you might experience pain, redness and swelling in the calf – this pain is made worse when walking or standing. If these symptoms are experienced you should seek medical help immediately.
Complications can occur if the clot breaks off and travels to the lungs, blocking the flow of blood. Breathlessness and chest pain can occur hours or days after the clot formation in the calf. This is a potentially fatal condition and urgent medical attention is required.
Not moving for long periods of time can increase the risk of DVT. The following factors can also add to your risk of developing a DVT:
Those in a high-risk category should see their doctor or pharmacist before they travel and discuss prevention.
Those at risk should try to exercise at least every hour on long journeys. Exercise the calf muscles by rotating your ankles. Correctly fitting anti-thrombosis stockings/socks increase blood flow, therefore lowering the risk of DVT. These special stocking/socks should be worn on all forms of travel when a passenger is sitting still for a long period of time. See your pharmacist for advice.
Due to restrictions on many flights across the globe those travelling with existing medical conditions need to be aware of these restrictions when travelling with medication.
As well as trying to follow these guidelines it is a good idea to carry a copy of your prescription or a letter from your doctor stating the amounts and types of medication verified for your use, including any essential non-prescription medication.
If you are a diabetic you should first try to get an exemption certificate from the airline you are travelling with – for this you will need to get a letter from your doctor stating your need for insulin.
The world is divided into 24 time zones. Jet lag happens when you cross over a number of time zones and disrupt the body’s normal ‘biological clock’. When you cross time zones, you arrive hours ahead or behind the time in the country you fly from. The body has to adjust to new times of light, darkness and meals and often to differences in temperature.
Your internal body clock controls when you are sleepy and when you are alert, as well as hunger, digestion, bowel habits, urine production and body temperature. This ‘biological clock’ is normally synchronised with your local time so that you feel hungry in the morning and sleepy in the evening. When you travel across time zones, the body needs time to adjust.
Symptoms of jet lag vary from person to person and depend on the distance travelled and number of time zones crossed. Symptoms you may experience include:
It takes about one day to recover for each time zone you cross and can take up to a week to fully adjust.
Before you fly try to get plenty of sleep in the days before you travel.
During your flight try to:
When you arrive:
Avoid sleeping until bedtime; do not nap during the day, as it will not help you adjust to the local time. Do not drink caffeine or alcohol. Do not eat a heavy meal before going to sleep (but do not go to bed hungry). A relaxing bath can help you feel sleepy before bed.
Eat your meals at the correct times for the new time zone. Have meals containing protein for breakfast and lunch to keep you alert and have a meal containing carbohydrates for dinner to help you sleep.
As well as giving you painful sunburn, too much sun can age your skin and increase your risk of getting skin cancer. Remember, the sun is extremely strong in many holiday destinations – don’t underestimate its power.
Stings and bites from insects are common. They often result in pain, redness, itching and swelling in the affected area. The skin may be broken and become infected if the bite area is scratched. If the bite appears infected (redness with or without pus, warmth, fever, or a red streak that spreads toward the body), see a doctor.
Treatment depends on the type of reaction. If there is only redness and pain at the site of the bite, application of ice is adequate treatment. Clean the area with soap and water to remove contaminated particles left behind by some insects (such as mosquitoes). Try not to scratch the area because this may cause the skin to break and an infection may develop. You may treat itching at the site of the bite with an over-the-counter antihistamine. Speak to your pharmacist for more information.
You can minimise your exposure to insect bites:
Most cases of travellers’ diarrhoea begins abruptly. The illness usually results in increased frequency, volume and weight of stool. Other common symptoms you may get are nausea, vomiting, stomach cramps, bloating, fever. In most cases, travellers’ diarrhoea clears up in 1-2 days without treatment.
Because you lose vital fluids, salts and minerals during a bout with traveller’s diarrhoea, you may become dehydrated. Children are especially vulnerable to dehydration and it can be severe. An oral rehydration solution is the best way to replace lost fluids. These solutions contain water and salts in specific proportions to replenish both fluids and electrolytes. They also contain glucose or another carbohydrate such as rice powder to enhance absorption in the intestinal tract. Ask your pharmacist to recommend a suitable product.
