Is it okay to take iron tablets on an empty stomach?

Iron tablets are best absorbed by the body when taken on an empty stomach or with a glass of orange juice with vitamin C. However, some people may experience stomach upset or vomiting when taken on an empty stomach. For such people, it is best to take them after a meal. (Iron tablets should not be taken with tea or milk, as they block the absorption of iron into the body).

Why does weight gain occur when thyroid hormone levels are low (Hypothyroidism)?

When thyroid hormone levels are low, the body's metabolism (metabolism) or the rate of energy burning decreases significantly. Due to this, the calories received by the body are stored as fat instead of being burned, and the body weight increases rapidly.

Can depression cause physical weakness?

Yes, definitely. When depression occurs, the levels of chemicals such as serotonin and dopamine that affect brain function decrease. This causes the body's activity, interest, and muscle strength to collapse, causing constant fatigue and weakness.

Why do diabetics feel tired all the time?

Diabetic patients do not have enough insulin or the body does not respond to insulin, so the glucose (sugar) in the blood cannot enter the cells to produce energy. Therefore, even though there is a lot of sugar in the blood, the cells do not get energy, so they feel constantly tired.

Is it appropriate to take multivitamin pills to avoid weakness in the limbs?

If you have a vitamin deficiency, it is appropriate to take multivitamins on medical advice. However, avoid taking pills without medical advice. This is because multivitamin pills will not be of any benefit if other reasons such as anemia or diabetes are responsible for the weakness in the body.

“Doctor, I’ve been feeling like I have no energy for a few months now. I can’t even get out of bed in the morning, I’m sleepy all day, and my whole body is tired. Do I have some kind of cancer, doctor? I can’t even do my work.”

Malini, a 38-year-old working mother who came to my clinic last week, spoke with tears in her eyes, looking down, and rubbing her neck. She was deeply embarrassed and terrified that she had a serious illness, like cancer.

I looked at Malini and smiled kindly, allaying her fears: “Malini, first of all, don’t worry. You don’t have cancer. Thousands of women in Sri Lanka feel this way about their bodies. It is caused by a few simple flaws in our bodies. So this is a condition that can be cured by laser. Let’s first do a blood test, and then start treatment.”

Malini's full blood count revealed that she had severe iron deficiency anemia. She was given iron supplements and advice on changing her diet, and she returned to the clinic a month later. She was very active and smiling that day.

So today, let's talk about the real medical causes, symptoms, and proper medical treatments behind the fatigue/lethargy that many people suffer from and that impairs their daily activities.
