Know How Higher Intake of Sodium Can Treat Lightheadedness

Greater sodium intake is widely viewed as an intervention for preventing lightheadedness when moving from seated to standing positions.

Higher sodium intake should not be used as a treatment for lightheadedness, say researchers challenging current guidelines for sodium consumption.

Lightheadedness while standing, known as postural lightheadedness, results from gravitational drop in blood pressure and is common among adults.

Greater sodium intake is widely viewed as an intervention for preventing lightheadedness when moving from seated to standing positions.

However, contrary to this recommendation, researchers at Beth Israel Deaconess Medical Centre (BIDMC) found that higher sodium intake, actually increases dizziness.

“Our study has clinical and research implications,” said Stephen Juraschek, researcher from BIDMC in Boston.

“Our results serve to caution health practitioners against recommending increased sodium intake as a universal treatment for lightheadedness. Additionally, our results demonstrate the need for additional research to understand the role of sodium, and more broadly of diet, on lightheadedness,” Juraschek said.

For the study, reported in The Journal of Clinical Hypertension, the team used data from the completed DASH-Sodium trial, a randomised crossover study that looked at the effects of three different sodium levels (1500, 2300, and 3300 mg/d) on participants’ blood pressure for four weeks.

While the trial showed that lower sodium led to decrease in blood pressure, it also suggested that concerns about lower level of sodium causing dizziness may not be scientifically correct.

The study also questioned recommendations to use sodium to treat lightheadedness, an intervention that could have negative effects on cardiovascular health.

“Health practitioners initiating sodium interventions for orthostatic symptoms now have some evidence that sodium might actually worsen symptoms,” Juraschek said.

“Clinicians should check on symptoms after initiation and even question the utility of this approach. More importantly, research is needed to understand the effects of sodium on physical function, particularly in older adults.” (IANS)

Here’s how Low-Dose Aspirin may Help Mothers Lower the Risk of Preterm Birth

Low-dose of aspirin regularly can help mothers lower the risk of preterm delivery

Daily low-dose aspirin, from as early as the sixth week of pregnancy through the 36th week, may lower the risk of preterm birth among first-time mothers, suggest the results of a clinical trial which involved women from several low and middle-income countries, including India.

The study, published in the journal The Lancet, involved more than 11,000 women. The results showed that women taking daily low-dose aspirin were 11 per cent less likely to deliver before the 37th week of pregnancy, compared to those given a placebo.

“Our results suggest that low-dose aspirin therapy in early pregnancy could provide an inexpensive way to lower the preterm birth rate in first-time mothers,” said study author Marion Koso-Thomas of the US National Institutes of Health’s Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD).

Preterm birth is the most common cause of infant death and the leading cause of long-term neurological disability in children.

According to the study authors, advances in newborn care have improved survival for preterm infants, but this care is limited or unavailable in many parts of the world.

Earlier studies have suggested that low-dose aspirin may reduce the risk of preterm birth and pre-eclampsia, a potentially life-threatening blood pressure disorder of pregnancy.

However, these studies were not large enough to statistically determine the therapy’s effectiveness in reducing preterm birth. The researchers enrolled 11,976 women with a first-time pregnancy from seven sites in India, Pakistan, Zambia, Democratic Republic of the Congo, Guatemala and Kenya.

Roughly half were assigned at random to receive 81 milligrams of aspirin daily; the other group received a daily placebo. Women were included in the study only if they maintained a pregnancy for more than 20 weeks.

Preterm birth (before 37 weeks) occurred in 11.6 per cent of the women who took aspirin and in 13.1 per cent of the women who took the placebo. Similarly, birth before 34 weeks (early preterm delivery) occurred in 3.3 per cent of the aspirin group and 4 per cent of the placebo group (a 25 per cent reduction).

Women in the aspirin group also had a lower rate of perinatal mortality (stillbirth or newborn death in the first seven days of life), compared to the placebo group (45.7 per 1,000 births vs 53.6 per 1,000 births).

The risk of high blood pressure disorders of pregnancy at term did not differ significantly between the groups. The low cost and safety of low-dose aspirin therapy suggests that it could be easily adapted for wide-scale use, suggested the study authors. (IANS)
