The Weight That's Quietly Dropping

Every week the call connects and your father's face fills the frame. Same spectacles, same kurta, same slightly impatient way of holding the phone too close. He is sitting, so you cannot see him stand. He is framed from the chest up, so you cannot see the belt pulled to a tighter notch, or the trousers that now need a fold at the waist. He says he is eating fine. And you hang up reassured, because he looked exactly like himself. This is the strange blind spot of loving a parent through a screen: you would instantly catch a cough, a tremor, a struggle to find a word, but weight, one of the body's most reliable signals, is almost invisible on a video call. A person can lose four or five kilograms and still look, from the shoulders up, entirely unchanged.

And that matters more than most families realise. Doctors have a clear line for this: an unplanned loss of about 5% of body weight over six to twelve months, weight the person did not set out to lose, is considered clinically significant and worth investigating. For a 70 kg parent, that threshold is just 3.5 kg. It is not the dramatic wasting we picture. It is a slightly looser blouse, a ring that spins, a face that has quietly narrowed. It is precisely because the change is so undramatic, so easy to explain away as "he was always slim" or "she eats less now that she's older," that it slips past a family for months.

Unexplained weight loss is not a diagnosis; it is the body raising a hand to say something has changed. Very often the cause is ordinary and fixable. A new tablet that flattened their appetite or altered taste. A sore tooth or an ill-fitting denture that makes chewing a chore, so they quietly stop eating anything that needs effort. A swallowing problem, a sluggish thyroid, a low mood that has taken the interest out of food, or the slow drift into cooking for one after a spouse is gone, the pattern we wrote about in an earlier letter. Occasionally, and this is exactly why it deserves a look rather than a shrug, steady weight loss is the first and only sign of something that is very treatable when caught early and far harder later. The point is never to frighten yourself. It is that a falling weight is a question worth asking a doctor, not a detail worth ignoring.

There is a second danger, too, one that exists even when the underlying cause turns out to be completely benign: the weight loss itself is hard on an older body. What an ageing parent loses first is muscle, and lost muscle means less strength, poorer balance, more falls, slower recovery from any illness, a weaker response to infection. Frailty feeds on itself, each kilogram gone making the next easier to lose. Catching a 3.5 kg drop early and reversing it is a small, manageable task. Trying to rebuild a parent after ten kilograms have melted away, along with the muscle and confidence that went with them, is a long and uphill one.

So the answer to a signal you cannot see on a call is simple: make it something you can measure. You do not need to be in the room to watch a number. A basic weighing scale by the bathroom door, a weight noted on the wall calendar on the first of every month, a photo of the display sent to you, and suddenly the invisible becomes a line you can track from anywhere on earth. And between the weigh-ins, listen for the proxies your parent mentions without thinking, the belt moved in a notch, the watch strap that now sits loose, the blouse taken to the tailor to be taken in, the offhand "all my clothes have become big." Those are not small talk. They are data, arriving disguised as conversation.
