leg pain

Treat leg pain with RICE

YOUR HEALTH — ?Dr Gita Mathai Aug 15, 2018 00:00 IST

As we age, one or both of our legs can pain. A slip or fall or even an awkward step can sprain the ankle. It bears half the weight of the upright body but is a relatively weak joint. If the ligaments are strained, swelling and pain occur. If the ligaments are torn, there may be bruising as well. The R.I.C.E. treatment (rest, application of ice every 20 minutes, compression with an elastocrepe bandage and elevation ) for 2-3 days will usually work. Medication such as paracetamol and ibuprofen help relieve the pain. If there is no improvement after three days, a fracture may have occurred.

If you have an active lifestyle, you can develop a sudden severe pain on the inside of the leg called "shin splints". It is more likely to occur if you have flat feet or use footwear unsuitable for activity or if muscles around the bone are overused. They can be relieved with ice packs and elevation of the legs. If shin splints are persistent, a stress fracture (hairline fracture) may have occurred.

Varicose veins appear as bluish swellings on the legs, usually on both sides and cause a dull, throbbing pain. They occur if valves in the veins are weak, making it difficult for blood to be pumped back into the heart from the legs. They are usually seen in people whose BMI (weight divided by height in metre squared) is greater than 30, in women during pregnancy or in those who sit or stand long hours for work. Wearing compression stockings, exercise and losing weight help.

Cramps occur as a sharp, unbearable pain, usually in the calf muscle. The muscle becomes tight and forms a hard lump which can be felt under the skin. It can be relieved by stretching and massage. It occurs with dehydration and lack of sodium or calcium. It usually goes away on its own. Recurrent cramps need medical evaluation.

Sciatica is a sharp shooting pain that extends from the lower back down the thigh, usually on one side. It is due to a slipped or herniated vertebral disc impinging on the nerves to the leg. It usually improves with OTC medication and physiotherapy. If it is persistent and incapacitating, surgery may be required.

Peripheral neuropathy may damage nerves in the thighs and feet. They may exhibit pricking or shooting pains that get worse at night. It is usually because of vitamin deficiencies, infections, nerve damage or diabetes. Treatment of the underlying cause is required in addition to specific medication.

If along with the pain in the legs there is swelling, change of colour in the overlying skin, fever, or no improvement after three days, a physician should be consulted.

water requirements

The liquid of life
Your health

Water makes up 75 per cent of the body weight of an infant and 55 per cent of an adult. Our body is composed of multiple complex cells which contain enzymes, electrolytes and electrical charges. All these function only in the presence of water. "Fasting unto death" (for political or religious reasons) will take two months if only food is avoided. It will take seven days or less if water is also withheld.

The exact amount of water required for healthy existence has not been accurately studied. Roughly, the amount required varies with age from around 700ml (1 cup=250ml) a day for infants to 3.8 litres (16 cups) for lactating women. Not all this fluid has to come from water.

Infants get much of their fluid requirement from milk. The electrolyte composition of breast milk is ideal for babies. Any tinned formula has to be reconstituted precisely as advised (usually one flat scoop for 30ml of water) Adding more or less powder will cause variations in the electrolyte composition. The sodium content can go up and down (hypo or hypernatremia, respectively), as the infants immature kidneys cannot regulate this effectively. After weaning, water comes from food, juices and, later in life, from tea and coffee.

The amount of water an adult needs depends on body composition (muscle:fat) outside temperature, humidity and level of activity. A labourer or marathon runner requires more fluids than a sedentary office worker. Before a workout, drink two cups of water to hydrate yourself. An active workout requires one cup of water every 20-30 minutes.

Older people may not be able to regulate their fluid intake relying on thirst alone. They may need to consciously drink water. School and college going youngsters (particularly girls) may suppress their thirst as they do not wish to use the restroom.

High coloured urine does not necessarily mean dehydration. The colour may be due to natural colours or additives in the food.

You can overhydrate by drinking too much water. This results in low sodium or hyponatremia. Headache and fatigue can be followed by muscle spasms or convulsions. Sportspersons can prevent this by adding a pinch of salt to their water or consuming isotonic sports drinks.

Dehydration is more dangerous. Concentration becomes poor, reaction time is increased, learning, memory, and retention are poor, and there may be mood swings. As dehydration progresses, organs can shut down, resulting in death.

Women should be conscious of their fluid intake during pregnancy as dehydration, especially in the last trimester, can precipitate urinary tract infections and premature labour. After delivery, good hydration means there is adequate breast milk for the baby.

Aids to memory

YOUR HEALTH - DR GITA MATHAI Apr 18, 2018 00:00 IST

Forgetfulness is a terrible thing. In children, it leads to poor grades. In older people, it leads to mislaid keys and forgotten appointments.

Now, scientists have found the basis of memory, using fancy contrast scans. As new information was processed, they could observe new synapses being formed between the neurons. Repetition made these connections stronger.

These days, both adults and children watch a great deal of television. The objects on TV appear to move because of the unrealistically rapid pace at which they are projected. "Reading" these images overworks the synapses and depletes brain chemicals. As little as an hour of TV a day negatively impacts the processing and retention of information. In young children, it raises the chances of developing attention deficit disorder by 10 per cent.

These neurochemicals are reformed during sleep. Adults and children do not sleep the required 7 and 10 hours respectively at night. A gradual deficit builds up, making remembering difficult.

Just like the body needs physical exercise to stay fit, the brain needs intellectual stimulation. It also requires healthy food, such as fruits and vegetables. Smoking has a negative effect while alcohol, in quantities greater than 30ml a day for women and 60ml for men, can permanently shrink brain cells.

Stress depletes brain chemicals and prevents them from reforming. Music, yoga, prayer, meditation or even just taking 20 deep breathes at a time, three or four times a day, are effective for destressing.

Recall and retention become more efficient if things are written down and then repeated loudly. This is because the brain is then stimulated in all three directions - graphics, audio and visual. Also, break down complicated tasks into simple steps which can be focussed on one at a time. Written notes are a great aid to memory.

Tired? Blame the T cells

Have you been feeling tired, lethargic, short on energy and unable to complete daily chores? While these complaints are common in all age groups, they are more likely in older people, especially women. The tiredness can also is expressed as daytime drowsiness.

That inexplicable tiredness should not be dismissed out of hand. It is not a natural part of ageing and though fatigue may be a component of a psychiatric illness such as depression, this should not be presumed to be the case without ruling out a plethora of medical problems.

In a small percentage of people - between 40 and 60 years of age and predominantly female - a mild flu can leave a debilitating fatigue which lasts for months. Despite investigations, no cause can be found. Till recently medical personnel did not take this seriously but now it has been identified as "chronic fatigue syndrome". A diagnosis is made if the condition has persisted for six months or longer. Exertion aggravates the symptoms, sleep is not refreshing despite long hours in bed, multiple muscles and joints pain but without redness or swelling. The head aches and a few lymph nodes may be enlarged.

The symptoms are now believed to be caused by an immune system malfunction, often following a trivial viral infection. The blood levels of cytokines are high, and the T cells needed to fight off infection function abnormally.

Treatment has to be individualised. Medications to treat pain, anxiety and depression, a healthy diet, vitamin supplements and sleep intervention are all helpful. Exercise has to be graded. "Pushing the limits" week by week, a little at a time, can help with the fatigue. Recovery is slow and may take a year or so. The important thing is to break up big jobs into little doable tasks, and to persist with the treatment.

candida infection

Decoding candida

Your Health

Dr Gita Mathai Feb 14, 2018 00:00 IST

The commonest fungus that affects humans belongs to the candida species. That is why the infection is called candida or thrush.

We are usually resistant to a thrush infection because of our natural immunity. Babies, the elderly and people whose immunity is compromised by HIV infection, cancer or treatment with steroids are unable to withstand the infection.

The spores thrive in the mouth, vagina, penis, and in the sweaty folds of the body - in the armpits, under the folds of the breast, in the groin and diaper areas of babies. They can grow rapidly, causing the area to become inflamed, red, scaly and itchy.

In the mouth and vagina, thrush is visible as curdy white patches that cannot be scraped off. It makes the foreskin of the penis inflamed and cracked. There may be a foul odour. Scratching causes the organism to be deposited under the nails and transported to other areas.

Prolonged sucking on pacifiers and bottle nipples can cause micro trauma to the mucous membrane of the mouth in babies, enabling candida to get a foothold. If the infant is on antibiotics, the protective microbes in the mouth can get suppressed, causing an overgrowth of candida. The infection can occur in breast-fed infants also and may be passed back and forth from nipple to mouth.

Diapers can promote the overgrowth of candida. The diaper area may be covered with red splotches or be scaly. It can occur because the baby is left in the soiled diaper too long or the baby or mother is on antibiotics.

Local applications of anti-fungal solutions or creams are usually all that is required for the infection to clear up.

Natural probiotics (like a tablespoon of curd) on an empty stomach in the morning will help to repopulate the body with good bacteria and prevent overgrowth of fungus.
