Updates records more than one time on laravel - laravel

Question

I am trying to update values in laravel. I have a userupdate profile api which I can update the values first time with given parameters and their values but 2nd time when I update same values it gives me user profile does not exist.
My Code is :
public function UpdateUserProfile(Request $request)
{
$id = $request->input('id');
$client_gender = $request->input('client_gender');
$client_age = $request->input('client_age');
$client_weight = $request->input('client_weight');
$client_height = $request->input('client_height');
$client_dob = $request->input('client_dob');
$profile= DB::table('clients')
->where('id',$id)
->update(['client_gender'=>$client_gender,'client_age'=>$client_age,'client_height'=>$client_height,'client_weight'=>$client_weight,'client_dob'=>$client_dob]);
if($profile)
{
$resultArray = ['status' => 'true', 'message' => 'User profile updated Successfully!'];
return Response::json( $resultArray, 200);
}
$resultArray = ['status' => 'false', 'message' => 'User profile does not exist!'];
return Response::json($resultArray, 400);}
first time when I update the value it gives me the response like this:
{
"status": "true",
"message": "User profile updated Successfully!"
}
and when I hit the update request through a postman it gives a 400 Bad request and response is :
{
"status": "false",
"message": "User profile does not exist!"
}

I'd recommend rewriting that function to look like the following; mostly because it reads better and uses the Model methods that are more commonly found in Laravel
public function UpdateUserProfile(Request $request)
{
// this code fails if there is no client with this id
$client = App\Client::findOrFail($request->id);
// attach new values for all of the attributes
$client->client_gender = $request->input('client_gender');
$client->client_age = $request->input('client_age');
$client->client_weight = $request->input('client_weight');
$client->client_height = $request->input('client_height');
$client->client_dob = $request->input('client_dob');
// save
$client->save();
return ['status' => 'true', 'message' => 'User profile updated Successfully!'];
}
